How to Create Structured Word Documents Using Python

Creating Word documents programmatically is a common requirement in Python applications. Reports, invoices, contracts, audit logs, and exported datasets are often expected to be delivered as editable .docx files rather than plain text or PDFs.
Unlike plain text output, a Word document is a structured document composed of sections, paragraphs, styles, and layout rules. When generating Word documents in Python, treating .docx files as simple text containers quickly leads to layout issues and maintenance problems.
This tutorial focuses on practical Word document creation in Python using Spire.Doc for Python. It demonstrates how to construct documents using Word’s native object model, apply formatting at the correct structural level, and generate .docx files that remain stable and editable as content grows.

1. Understanding Word Document Structure in Python
Before writing code, it is important to understand how a Word document is structured internally.
A .docx file is not a linear stream of text. It consists of multiple object layers, each with a specific responsibility:
- Document – the root container for the entire file
- Section – defines page-level layout such as size, margins, and orientation
- Paragraph – represents a logical block of text
- Run (TextRange) – an inline segment of text with character formatting
- Style – a reusable formatting definition applied to paragraphs or runs
When you create a Word document in Python, you are explicitly constructing this hierarchy in code. Formatting and layout behave predictably only when content is added at the appropriate level.
Spire.Doc for Python provides direct abstractions for these elements, allowing you to work with Word documents in a way that closely mirrors how Word itself organizes content.
2. Creating a Basic Word Document in Python
This section shows how to generate a valid Word document in Python using Spire.Doc. The example focuses on establishing the correct document structure and essential workflow.
Installing Spire.Doc for Python
pip install spire.doc
Alternatively, you can download Spire.Doc for Python and integrate it manually.
Creating a Simple .docx File
from spire.doc import Document, FileFormat
# Create the document container
document = Document()
# Add a section (defines page-level layout)
section = document.AddSection()
# Add a paragraph to the section
paragraph = section.AddParagraph()
paragraph.AppendText(
"This document was generated using Python. "
"It demonstrates basic Word document creation with Spire.Doc."
)
# Save the document
document.SaveToFile("basic_document.docx", FileFormat.Docx)
document.Close()
This example creates a minimal but valid .docx file that can be opened in Microsoft Word. It demonstrates the essential workflow: creating a document, adding a section, inserting a paragraph, and saving the file.

From a technical perspective:
- The Document object represents the Word file structure and manages its content.
- The Section defines the page-level layout context for paragraphs.
- The Paragraph contains the visible text and serves as the basic unit for all paragraph-level formatting.
All Word documents generated with Spire.Doc follow this same structural pattern, which forms the foundation for more advanced operations.
3. Adding and Formatting Text Content
Text in a Word document is organized hierarchically. Formatting can be applied at the paragraph level (controlling alignment, spacing, indentation, etc.) or the character level (controlling font, size, color, bold, italic, etc.). Styles provide a convenient way to store these formatting settings so they can be consistently applied to multiple paragraphs or text ranges without redefining the formatting each time. Understanding the distinction between paragraph formatting, character formatting, and styles is essential when creating or editing Word documents in Python.
Adding and Setting Paragraph Formatting
All visible text in a Word document must be added through paragraphs, which serve as containers for text and layout. Paragraph-level formatting controls alignment, spacing, and indentation, and can be set directly via the Paragraph.Format property. Character-level formatting, such as font size, bold, or color, can be applied to text ranges within the paragraph via the TextRange.CharacterFormat property.
from spire.doc import Document, HorizontalAlignment, FileFormat, Color
document = Document()
section = document.AddSection()
# Add the title paragraph
title = section.AddParagraph()
title.Format.HorizontalAlignment = HorizontalAlignment.Center
title.Format.AfterSpacing = 20 # Space after the title
title.Format.BeforeSpacing = 20
title_range = title.AppendText("Monthly Sales Report")
title_range.CharacterFormat.FontSize = 18
title_range.CharacterFormat.Bold = True
title_range.CharacterFormat.TextColor = Color.get_LightBlue()
# Add the body paragraph
body = section.AddParagraph()
body.Format.FirstLineIndent = 20
body_range = body.AppendText(
"This report provides an overview of monthly sales performance, "
"including revenue trends across different regions and product categories. "
"The data presented below is intended to support management decision-making."
)
body_range.CharacterFormat.FontSize = 12
# Save the document
document.SaveToFile("formatted_paragraph.docx", FileFormat.Docx)
document.Close()
Below is a preview of the generated Word document.

Technical notes
- Paragraph.Format sets alignment, spacing, and indentation for the entire paragraph
- AppendText() returns a TextRange object, which allows character-level formatting (font size, bold, color)
- Every paragraph must belong to a section, and paragraph order determines reading flow and pagination
Creating and Applying Styles
Styles allow you to define paragraph-level and character-level formatting once and reuse it across the document. They can store alignment, spacing, font, and text emphasis, making formatting more consistent and easier to maintain. Word documents support both custom styles and built-in styles, which must be added to the document before being applied.
Creating and Applying a Custom Paragraph Style
from spire.doc import (
Document, HorizontalAlignment, BuiltinStyle,
TextAlignment, ParagraphStyle, FileFormat
)
document = Document()
# Create a new custom paragraph style
custom_style = ParagraphStyle(document)
custom_style.Name = "CustomStyle"
custom_style.ParagraphFormat.HorizontalAlignment = HorizontalAlignment.Center
custom_style.ParagraphFormat.TextAlignment = TextAlignment.Auto
custom_style.CharacterFormat.Bold = True
custom_style.CharacterFormat.FontSize = 20
# Inherit properties from a built-in heading style
custom_style.ApplyBaseStyle(BuiltinStyle.Heading1)
# Add the style to the document
document.Styles.Add(custom_style)
# Apply the custom style
title_para = document.AddSection().AddParagraph()
title_para.ApplyStyle(custom_style.Name)
title_para.AppendText("Regional Performance Overview")
Adding and Applying Built-in Styles
# Add a built-in style to the document
built_in_style = document.AddStyle(BuiltinStyle.Heading2)
document.Styles.Add(built_in_style)
# Apply the built-in style
heading_para = document.Sections.get_Item(0).AddParagraph()
heading_para.ApplyStyle(built_in_style.Name)
heading_para.AppendText("Sales by Region")
document.SaveToFile("document_styles.docx", FileFormat.Docx)
Preview of the generated Word document.

Technical Explanation
- ParagraphStyle(document) creates a reusable style object associated with the current document
- ParagraphFormat controls layout-related settings such as alignment and text flow
- CharacterFormat defines font-level properties like size and boldness
- ApplyBaseStyle() allows the custom style to inherit semantic meaning and default behavior from a built-in Word style
- Adding the style to document.Styles makes it available for use across all sections
Built-in styles, such as Heading 2, can be added explicitly and applied in the same way, ensuring the document remains compatible with Word features like outlines and tables of contents.
4. Inserting Images into a Word Document
In Word’s document model, images are embedded objects that belong to paragraphs, which ensures they flow naturally with text. Paragraph-anchored images adjust pagination automatically and maintain relative positioning when content changes.
Adding an Image to a Paragraph
from spire.doc import Document, TextWrappingStyle, HorizontalAlignment, FileFormat
document = Document()
section = document.AddSection()
section.AddParagraph().AppendText("\r\n\r\nExample Image\r\n")
# Insert an image
image_para = section.AddParagraph()
image_para.Format.HorizontalAlignment = HorizontalAlignment.Center
image = image_para.AppendPicture("Screen.jpg")
# Set the text wrapping style
image.TextWrappingStyle = TextWrappingStyle.Square
# Set the image size
image.Width = 350
image.Height = 200
# Set the transparency
image.FillTransparency(0.7)
# Set the horizontal alignment
image.HorizontalAlignment = HorizontalAlignment.Center
document.SaveToFile("document_images.docx", FileFormat.Docx)
Preview of the generated Word document.

Technical details
- AppendPicture() inserts the image into the paragraph, making it part of the text flow
- TextWrappingStyle determines how surrounding text wraps around the image
- Width and Height control the displayed size of the image
- FillTransparency() sets the image opacity
- HorizontalAlignment can center the image within the paragraph
Adding images to paragraphs ensures they behave like part of the text flow.
- Pagination adjusts automatically when images change size.
- Surrounding text reflows correctly when content is edited.
- When exporting to formats like PDF, images maintain their relative position.
These behaviors are consistent with Word’s handling of inline images.
For more advanced image operations in Word documents using Python, see how to insert images into a Word document with Python for a complete guide.
5. Creating and Populating Tables
Tables are commonly used to present structured data such as reports, summaries, and comparisons.
Internally, a table consists of rows, cells, and paragraphs inside each cell.
Creating and Formatting a Table in a Word Document
from spire.doc import Document, DefaultTableStyle, FileFormat, AutoFitBehaviorType
document = Document()
section = document.AddSection()
section.AddParagraph().AppendText("\r\n\r\nExample Table\r\n")
# Define the table data
table_headers = ["Region", "Product", "Units Sold", "Unit Price ($)", "Total Revenue ($)"]
table_data = [
["North", "Laptop", 120, 950, 114000],
["North", "Smartphone", 300, 500, 150000],
["South", "Laptop", 80, 950, 76000],
["South", "Smartphone", 200, 500, 100000],
["East", "Laptop", 150, 950, 142500],
["East", "Smartphone", 250, 500, 125000],
["West", "Laptop", 100, 950, 95000],
["West", "Smartphone", 220, 500, 110000]
]
# Add a table to the section
table = section.AddTable()
table.ResetCells(len(table_data) + 1, len(table_headers))
# Populate table headers
for col_index, header in enumerate(table_headers):
header_range = table.Rows[0].Cells[col_index].AddParagraph().AppendText(header)
header_range.CharacterFormat.FontSize = 14
header_range.CharacterFormat.Bold = True
# Populate table data
for row_index, row_data in enumerate(table_data):
for col_index, cell_data in enumerate(row_data):
data_range = table.Rows[row_index + 1].Cells[col_index].AddParagraph().AppendText(str(cell_data))
data_range.CharacterFormat.FontSize = 12
# Apply a default table style and auto-fit columns
table.ApplyStyle(DefaultTableStyle.ColorfulListAccent6)
table.AutoFit(AutoFitBehaviorType.AutoFitToContents)
document.SaveToFile("document_tables.docx", FileFormat.Docx)
Preview of the generated Word document.

Technical details
- Section.AddTable() inserts the table into the section content flow
- ResetCells(rows, columns) defines the table grid explicitly
- Table[row, column] or Table.Rows[row].Cells[col] returns a TableCell
Tables in Word are designed so that each cell acts as an independent content container. Text is always inserted through paragraphs, and each cell can contain multiple paragraphs, images, or formatted text. This structure allows tables to scale from simple grids to complex report layouts, making them flexible for reports, summaries, or any structured content.
For more detailed examples and advanced operations using Python, such as dynamically generating tables, merging cells, or formatting individual cells, see how to insert tables into Word documents with Python for a complete guide.
6. Adding Headers and Footers
Headers and footers in Word are section-level elements. They are not part of the main content flow and do not affect body pagination.
Each section owns its own header and footer, which allows different parts of a document to display different repeated content.
Adding Headers and Footers in a Section
from spire.doc import Document, FileFormat, HorizontalAlignment, FieldType, BreakType
document = Document()
section = document.AddSection()
section.AddParagraph().AppendBreak(BreakType.PageBreak)
# Add a header
header = section.HeadersFooters.Header
header_para1 = header.AddParagraph()
header_para1.AppendText("Monthly Sales Report").CharacterFormat.FontSize = 12
header_para1.Format.HorizontalAlignment = HorizontalAlignment.Left
header_para2 = header.AddParagraph()
header_para2.AppendText("Company Name").CharacterFormat.FontSize = 12
header_para2.Format.HorizontalAlignment = HorizontalAlignment.Right
# Add a footer with page numbers
footer = section.HeadersFooters.Footer
footer_para = footer.AddParagraph()
footer_para.Format.HorizontalAlignment = HorizontalAlignment.Center
footer_para.AppendText("Page ").CharacterFormat.FontSize = 12
footer_para.AppendField("PageNum", FieldType.FieldPage).CharacterFormat.FontSize = 12
footer_para.AppendText(" of ").CharacterFormat.FontSize = 12
footer_para.AppendField("NumPages", FieldType.FieldNumPages).CharacterFormat.FontSize = 12
document.SaveToFile("document_header_footer.docx", FileFormat.Docx)
document.Dispose()
Preview of the generated Word document.

Technical notes
- section.HeadersFooters.Header / .Footer provides access to header/footer of the section
- AppendField() inserts dynamic fields like FieldPage or FieldNumPages to display dynamic content
Headers and footers are commonly used for report titles, company information, and page numbering. They update automatically as the document changes and are compatible with Word, PDF, and other export formats.
For more detailed examples and advanced operations, see how to insert headers and footers in Word documents with Python.
7. Controlling Page Layout with Sections
In Spire.Doc for Python, all page-level layout settings are managed through the Section object. Page size, orientation, and margins are defined by the section’s PageSetup and apply to all content within that section.
Configuring Page Size and Orientation
from spire.doc import PageSize, PageOrientation
section.PageSetup.PageSize = PageSize.A4()
section.PageSetup.Orientation = PageOrientation.Portrait
Technical explanation
- PageSetup is a layout configuration object owned by the Section
- PageSize defines the physical dimensions of the page
- Orientation controls whether pages are rendered in portrait or landscape mode
PageSetup defines the layout for the entire section. All paragraphs, tables, and images added to the section will follow these settings. Changing PageSetup in one section does not affect other sections in the document, allowing different sections to have different page layouts.
Setting Page Margins
section.PageSetup.Margins.Top = 50
section.PageSetup.Margins.Bottom = 50
section.PageSetup.Margins.Left = 60
section.PageSetup.Margins.Right = 60
Technical explanation
- Margins defines the printable content area for the section
- Margin values are measured in document units
Margins control the body content area for the section. They are evaluated at the section level, so you do not need to set them for individual paragraphs, and header/footer areas are not affected.
Using Multiple Sections for Different Layouts
When a document requires different page layouts, additional sections must be created.
landscape_section = document.AddSection()
landscape_section.PageSetup.Orientation = PageOrientation.Landscape
Technical notes
- AddSection() creates a new section and appends it to the document
- Each section maintains its own PageSetup, headers, and footers
- Content added after this call belongs to the new section
Using multiple sections allows mixing portrait and landscape pages or applying different layouts within a single Word document.
Below is an example preview of the above settings in a Word document:

8. Setting Document Properties and Metadata
In addition to visible content, Word documents expose metadata through built-in document properties. These properties are stored at the document level and do not affect layout or rendering.
Assigning Built-in Document Properties
document.BuiltinDocumentProperties.Title = "Monthly Sales Report"
document.BuiltinDocumentProperties.Author = "Data Analytics System"
document.BuiltinDocumentProperties.Company = "Example Corp"
Technical notes
BuiltinDocumentPropertiesprovides access to standard document properties- Properties such as
Title,Author, andCompanycan be set programmatically
Document properties are commonly used for file indexing, search, document management, and audit workflows. In addition to built-in properties, Word documents support other metadata such as Keywords, Subject, Comments, and Hyperlink base. You can also define custom properties using Document.CustomDocumentProperties.
For a guide on managing document custom properties with Python, see how to manage custom metadata in Word documents with Python.
9. Saving, Exporting, and Performance Considerations
After constructing a Word document in memory, the final step is saving or exporting it to the required output format. Spire.Doc for Python supports multiple export formats through a unified API, allowing the same document structure to be reused without additional formatting logic.
Saving and Exporting Word Documents in Multiple Formats
A document can be saved as DOCX for editing or exported to other commonly used formats for distribution.
from spire.doc import FileFormat
document.SaveToFile("output.docx", FileFormat.Docx)
document.SaveToFile("output.pdf", FileFormat.PDF)
document.SaveToFile("output.html", FileFormat.Html)
document.SaveToFile("output.rtf", FileFormat.Rtf)
The export process preserves document structure, including sections, tables, images, headers, and footers, ensuring consistent layout across formats. Check out all the supported formats in the FileFormat enumeration.
Performance Considerations for Document Generation
For scenarios involving frequent or large-scale Word document generation, performance can be improved by:
- Reusing document templates and styles
- Avoiding unnecessary section creation
- Writing documents to disk only after all content has been generated
- After saving or exporting, explicitly releasing resources using document.Close()
When generating many similar documents with different data, mail merge is more efficient than inserting content programmatically for each file. Spire.Doc for Python provides built-in mail merge support for batch document generation. For details, see how to generate Word documents in bulk using mail merge in Python.
Saving and exporting are integral parts of Word document generation in Python. By using Spire.Doc for Python’s export capabilities and following basic performance practices, Word documents can be generated efficiently and reliably for both individual files and batch workflows.
10. Common Pitfalls When Creating Word Documents in Python
The following issues frequently occur when generating Word documents programmatically.
Treating Word Documents as Plain Text
Issue Formatting breaks when content length changes.
Recommendation Always work with sections, paragraphs, and styles rather than inserting raw text.
Hard-Coding Formatting Logic
Issue Global layout changes require editing multiple code locations.
Recommendation Centralize formatting rules using styles and section-level configuration.
Ignoring Section Boundaries
Issue Margins or orientation changes unexpectedly affect the entire document.
Recommendation Use separate sections to isolate layout rules.
11. Conclusion
Creating Word documents in Python involves more than writing text to a file. A .docx document is a structured object composed of sections, paragraphs, styles, and embedded elements.
By using Spire.Doc for Python and aligning code with Word’s document model, you can generate editable, well-structured Word files that remain stable as content and layout requirements evolve. This approach is especially suitable for backend services, reporting pipelines, and document automation systems.
For scenarios involving large documents or document conversion requirements, a licensed version is required.
Create Excel Files in Python: From Basics to Automation

Creating Excel files in Python is a common requirement in data-driven applications. When application data needs to be delivered in a format that business users can easily review and share, Excel remains one of the most practical and widely accepted choices.
In real projects, generating an Excel file with Python is often the starting point of an automated process. Data may come from databases, APIs, or internal services, and Python is responsible for turning that data into a structured Excel file that follows a consistent layout and naming convention.
This article shows how to create Excel files in Python, from generating a workbook from scratch, to writing data, applying basic formatting, and updating existing files when needed. All examples are presented from a practical perspective, focusing on how Excel files are created and used in real automation scenarios.

1. Typical Scenarios for Creating Excel Files with Python
Creating Excel files with Python usually happens as part of a larger system rather than a standalone task. Common scenarios include:
- Generating daily, weekly, or monthly business reports
- Exporting database query results for analysis or auditing
- Producing Excel files from backend services or batch jobs
- Automating data exchange between internal systems or external partners
In these situations, Python is often used to generate Excel files automatically, helping teams reduce manual effort while ensuring data consistency and repeatability.
2. Environment Setup: Preparing to Create Excel Files in Python
In this tutorial, we use Free Spire.XLS for Python to demonstrate Excel file operations. Before generating Excel files with Python, ensure that the development environment is ready.
Python Version
Any modern Python 3.x version is sufficient for Excel automation tasks.
Free Spire.XLS for Python can be installed via pip:
pip install spire.xls.free
You can also download Free Spire.XLS for Python and include it in your project manually.
The library works independently of Microsoft Excel, which makes it suitable for server environments, scheduled jobs, and automated workflows where Excel is not installed.
3. Creating a New Excel File from Scratch in Python
This section focuses on creating an Excel file from scratch using Python. The goal is to define a basic workbook structure, including worksheets and header rows, before any data is written.
By generating the initial layout programmatically, you can ensure that all output files share the same structure and are ready for later data population.
Example: Creating a Blank Excel Template
from spire.xls import Workbook, FileFormat
# Initialize a new workbook
workbook = Workbook()
# Access the default worksheet
sheet = workbook.Worksheets[0]
sheet.Name = "Template"
# Add a placeholder title
sheet.Range["B2"].Text = "Monthly Report Template"
# Save the Excel file
workbook.SaveToFile("template.xlsx", FileFormat.Version2016)
workbook.Dispose()
The preview of the template file:

In this example:
- Workbook() creates a new Excel workbook that already contains three default worksheets.
- The first worksheet is accessed via Worksheets[0] and renamed to define the basic structure.
- The Range[].Text property writes text to a specific cell, allowing you to set titles or placeholders before real data is added.
- The SaveToFile() method saves the workbook to an Excel file. And FileFormat.Version2016 specifies the Excel version or format to use.
Creating Excel Files with Multiple Worksheets in Python
In Python-based Excel generation, a single workbook can contain multiple worksheets to organize related data logically. Each worksheet can store a different data set, summary, or processing result within the same file.
The following example shows how to create an Excel file with multiple worksheets and write data to each one.
from spire.xls import Workbook, FileFormat
workbook = Workbook()
# Default worksheet
data_sheet = workbook.Worksheets[0]
data_sheet.Name = "Raw Data"
# Remove the second default worksheet
workbook.Worksheets.RemoveAt(1)
# Add a summary worksheet
summary_sheet = workbook.Worksheets.Add("Summary")
summary_sheet.Range["A1"].Text = "Summary Report"
workbook.SaveToFile("multi_sheet_report.xlsx", FileFormat.Version2016)
workbook.Dispose()
This pattern is commonly combined with read/write workflows, where raw data is imported into one worksheet and processed results are written to another.
Excel File Formats in Python Automation
When creating Excel files programmatically in Python, XLSX is the most commonly used format and is fully supported by modern versions of Microsoft Excel. It supports worksheets, formulas, styles, and is suitable for most automation scenarios.
In addition to XLSX, Spire.XLS for Python supports generating several common Excel formats, including:
- XLSX – the default format for modern Excel automation
- XLS – legacy Excel format for compatibility with older systems
- CSV – plain-text format often used for data exchange and imports
In this article, all examples use the XLSX format, which is recommended for report generation, structured data exports, and template-based Excel files. You can check the FileFormat enumeration for a complete list of supported formats.
4. Writing Structured Data to an XLSX File Using Python
In real applications, data written to Excel rarely comes from hard-coded lists. It is more commonly generated from database queries, API responses, or intermediate processing results.
A typical pattern is to treat Excel as the final delivery format for already-structured data.
Python Example: Generating a Monthly Sales Report from Application Data
Assume your application has already produced a list of sales records, where each record contains product information and calculated totals. In this example, sales data is represented as a list of dictionaries, simulating records returned from an application or service layer.
from spire.xls import Workbook
workbook = Workbook()
sheet = workbook.Worksheets[0]
sheet.Name = "Sales Report"
headers = ["Product", "Quantity", "Unit Price", "Total Amount"]
for col, header in enumerate(headers, start=1):
sheet.Range[1, col].Text = header
# Data typically comes from a database or service layer
sales_data = [
{"product": "Laptop", "qty": 15, "price": 1200},
{"product": "Monitor", "qty": 30, "price": 250},
{"product": "Keyboard", "qty": 50, "price": 40},
{"product": "Mouse", "qty": 80, "price": 20},
{"product": "Headset", "qty": 100, "price": 10}
]
row = 2
for item in sales_data:
sheet.Range[row, 1].Text = item["product"]
sheet.Range[row, 2].NumberValue = item["qty"]
sheet.Range[row, 3].NumberValue = item["price"]
sheet.Range[row, 4].NumberValue = item["qty"] * item["price"]
row += 1
workbook.SaveToFile("monthly_sales_report.xlsx")
workbook.Dispose()
The preview of the monthly sales report:

In this example, text values such as product names are written using the CellRange.Text property, while numeric fields use CellRange.NumberValue. This ensures that quantities and prices are stored as numbers in Excel, allowing proper calculation, sorting, and formatting.
This approach scales naturally as the dataset grows and keeps business logic separate from Excel output logic. For more Excel writing examples, please refer to the How to Automate Excel Writing in Python.
5. Formatting Excel Data for Real-World Reports in Python
In real-world reporting, Excel files are often delivered directly to stakeholders. Raw data without formatting can be difficult to read or interpret.
Common formatting tasks include:
- Making header rows visually distinct
- Applying background colors or borders
- Formatting numbers and currencies
- Automatically adjusting column widths
The following example demonstrates how these common formatting operations can be applied together to improve the overall readability of a generated Excel report.
Python Example: Improving Excel Report Readability
from spire.xls import Workbook, Color, LineStyleType
# Load the created Excel file
workbook = Workbook()
workbook.LoadFromFile("monthly_sales_report.xlsx")
# Get the first worksheet
sheet = workbook.Worksheets[0]
# Format header row
header_range = sheet.Range.Rows[0] # Get the first used row
header_range.Style.Font.IsBold = True
header_range.Style.Color = Color.get_LightBlue()
# Apply currency format
sheet.Range["C2:D6"].NumberFormat = "$#,##0.00"
# Format data rows
for i in range(1, sheet.Range.Rows.Count):
if i % 2 == 0:
row_range = sheet.Range[i, 1, i, sheet.Range.Columns.Count]
row_range.Style.Color = Color.get_LightGreen()
else:
row_range = sheet.Range[i, 1, i, sheet.Range.Columns.Count]
row_range.Style.Color = Color.get_LightYellow()
# Add borders to data rows
sheet.Range["A2:D6"].BorderAround(LineStyleType.Medium, Color.get_LightBlue())
# Auto-fit column widths
sheet.AllocatedRange.AutoFitColumns()
# Save the formatted Excel file
workbook.SaveToFile("monthly_sales_report_formatted.xlsx")
workbook.Dispose()
The preview of the formatted monthly sales report:

While formatting is not strictly required for data correctness, it is often expected in business reports that are shared or archived. Check How to Format Excel Worksheets with Python for more advanced formatting techniques.
6. Reading and Updating Existing Excel Files in Python Automation
Updating an existing Excel file usually involves locating the correct row before writing new values. Instead of updating a fixed cell, automation scripts often scan rows to find matching records and apply updates conditionally.
Python Example: Updating an Excel File
from spire.xls import Workbook
workbook = Workbook()
workbook.LoadFromFile("monthly_sales_report.xlsx")
sheet = workbook.Worksheets[0]
# Locate the target row by product name
for row in range(2, sheet.LastRow + 1):
product_name = sheet.Range[row, 1].Text
if product_name == "Laptop":
sheet.Range[row, 5].Text = "Reviewed"
break
sheet.Range["E1"].Text = "Status"
workbook.SaveToFile("monthly_sales_report_updated.xlsx")
workbook.Dispose()
The preview of the updated monthly sales report:

7. Combining Read and Write Operations in a Single Workflow
When working with imported Excel files, raw data is often not immediately suitable for reporting or further analysis. Common issues include duplicated records, inconsistent values, or incomplete rows.
This section demonstrates how to read existing Excel data, normalize it, and write the processed result to a new file using Python.
In real-world automation systems, Excel files are often used as intermediate data carriers rather than final deliverables.
They may be imported from external platforms, manually edited by different teams, or generated by legacy systems before being processed further.
As a result, raw Excel data frequently contains issues such as:
- Multiple rows for the same business entity
- Inconsistent or non-numeric values
- Empty or incomplete records
- Data structures that are not suitable for reporting or analysis
A common requirement is to read unrefined Excel data, apply normalization rules in Python, and write the cleaned results into a new worksheet that downstream users can rely on.
Python Example: Normalizing and Aggregating Imported Sales Data
In this example, a raw sales Excel file contains multiple rows per product.
The goal is to generate a clean summary worksheet where each product appears only once, with its total sales amount calculated programmatically.
from spire.xls import Workbook, Color
workbook = Workbook()
workbook.LoadFromFile("raw_sales_data.xlsx")
source = workbook.Worksheets[0]
summary = workbook.Worksheets.Add("Summary")
# Define headers for the normalized output
summary.Range["A1"].Text = "Product"
summary.Range["B1"].Text = "Total Sales"
product_totals = {}
# Read raw data and aggregate values by product
for row in range(2, source.LastRow + 1):
product = source.Range[row, 1].Text
value = source.Range[row, 4].Value
# Skip incomplete or invalid rows
if not product or value is None:
continue
try:
amount = float(value)
except ValueError:
continue
if product not in product_totals:
product_totals[product] = 0
product_totals[product] += amount

Quickly Convert Nested XML Data to Excel Without Errors
Table of Contents

Converting XML to XLSX is a common requirement in data processing, reporting workflows, and system integration tasks. XML remains one of the most commonly used formats for structured or semi-structured data, but Excel’s XLSX format is far more convenient for analysis, filtering, visualization, and sharing with non-technical users.
Although the basic idea of transforming XML files into XLSX files sounds simple, real-world XML files vary widely in structure. Some resemble clean database tables, while others contain deeply nested nodes, attributes, or mixed content.
This guide provides a detailed, practical explanation of how to convert XML to XLSX using online tools, Microsoft Excel, and Python automation. It also discusses how to handle complex scenarios such as large datasets, nested elements, optional fields, and reverse conversion from XLSX back to XML.
Methods Overview:
- Online XML to XLSX Converters
- Excel XML Import Features
- Convert XML to XLSX Using Python Automation
- Custom Scripts or APIs for Enterprise Workflows
1. Understanding XML to XLSX Conversion
XML (Extensible Markup Language) is a simple text format that stores data using tags, forming a tree-like structure where parent elements contain children, and information may appear as either elements or attributes. XLSX, by contrast, is strictly row-and-column based, so converting XML to XLSX means flattening this tree into a table while keeping the data meaningful.
For straightforward XML—for example, a file with repeated <item> nodes—each node naturally becomes a row and its children become columns. But real-world XML often contains:
- nested details
- nodes that appear only in some records
- data stored in attributes
- namespaces used in enterprise systems
Such variations require decisions on how to flatten the hierarchy. Some tools do this automatically, while others need manual mapping. This guide covers both simple and complex cases, including how to convert XML to XLSX without opening Excel, which is common in automated workflows.
2. Method 1: Convert XML to XLSX Online
Online XML-to-XLSX converters—such as Convertion Tools, AConvert, or DataConverter.io—are convenient when you need a quick transformation without installing software. The process is typically very simple:
-
Visit a website that supports XML-to-XLSX conversion(such as DataConverter.io).

-
Upload your XML file or paste the XML string.
-
Some converter allow you to edit the mapping before conversion.

-
Click Download to download the generated .xlsx file.
This method works well for one-time tasks and for XML files with straightforward structures where automatic mapping is usually accurate.
Advantages
- Fast, no installation required.
- Suitable for simple or moderate XML structures.
- Ideal for one-time or occasional conversions.
Limitations
- Limited understanding of schemas, namespaces, and nested hierarchies.
- Deep XML may be flattened incorrectly, produce generic column names, or lose optional fields.
- Upload size limits and possible browser freezes with large files.
Despite these constraints, online tools remain a practical choice for quick, small-scale XML-to-XLSX conversions.

3. Method 2: Convert XML to XLSX in Excel
Excel provides native support for XML import, and for many users, this is the most transparent and controllable method. When used properly, Excel can read XML structures, apply customizable mappings, and save the converted result directly as an XLSX file.
3.1 Opening XML Directly in Excel
When you open an XML file through File → Open, Excel attempts to infer a schema and convert the data into a table. The correct sequence for this method is:
-
Go to File → Open and select the XML file.
-
When prompted, choose “As an XML table”.

-
Excel loads the XML and automatically maps child nodes to columns.
This works well for “flat” XML structures, where each repeating element corresponds neatly to a row. However, hierarchical XML often causes issues: nested nodes may be expanded into repeated columns, or Excel may prompt you to define an XML table manually if it cannot determine a clear mapping.
This direct-open method remains useful when the XML resembles a database-style list of records and you need a fast way to inspect or work with the data.
3.2 Importing XML via Excel’s Data Tab
For structured XML files—especially those based on XSD schemas—Excel provides a more user-friendly import method through the Data tab. This approach gives you control over how XML elements are mapped to the worksheet without manually using the XML Source pane.
Steps:
-
Open an Excel workbook or create a new one.
-
Go to Data → Get Data → From File → From XML.

-
Select your XML file and click Import.
-
Click Transform Data in the pop-up window.
-
In the Power Query Editor window, select the elements or tables you want to load.

-
Click Close & Load to save the changes, and the converted data will appear in a new worksheet.
This method allows Excel to automatically interpret the XML structure and map it into a table. It works well for hierarchical XML because you can select which sections to load, keeping optional fields and relationships intact.
This approach is especially useful for:
- Importing government e-form data
- Working with ERP/CRM exported XML
- Handling industry-specific standards such as UBL or HL7
By using this workflow, you can efficiently control how XML data is represented in Excel while minimizing manual mapping steps.
3.3 Saving the Imported XML Data as an XLSX File
Once the XML data has been successfully imported—whether by directly opening the XML file or using Data → Get Data → From XML—the final step is simply saving the workbook in Excel’s native .xlsx format. At this stage, the data behaves like any other Excel table, meaning you can freely adjust column widths, apply filters, format cells, or add formulas.
To save the converted XML as an XLSX file:
- Go to File → Save As.
- Choose Excel Workbook (*.xlsx) as the file type.
- Specify a location and click Save.
Below is a preview of the Excel table imported from XML:

If the XML file is based on an XSD schema and the mapping is preserved, Excel can even export the modified worksheet back to XML. However, for deeply nested XML structures, some preprocessing or manual adjustments might still be required before export.
4. Method 3: Convert XML to XLSX Using Python
Python is an excellent choice for converting XML to XLSX when you require automation, large-scale processing, or the ability to perform XML to XLSX conversion without opening Excel. Python scripts can run on servers, schedule tasks, and handle hundreds or thousands of XML files consistently.
4.1 Parsing XML in Python
Parsing XML is the first step in the workflow. Python’s xml.etree.ElementTree or lxml libraries provide event-based or tree-based parsing. They allow you to walk through each node, extract attributes, handle namespaces, and process deeply nested data.
The main challenge is defining how each XML node maps to an Excel row. Most workflows use either:
- a predefined mapping (e.g., a “schema” defined in code), or
- an auto-flattening logic that recursively converts nodes into columns.
Core XML Parsing Example:
The following Python code demonstrates how to parse an XML file and flatten it into a list of dictionaries, which can be used to generate an XLSX file.
import xml.etree.ElementTree as ET
xml_file = "Orders.xml"
# Recursively flatten an XML element into a flat dictionary
def flatten(e, prefix=""):
r = {}
# Add attributes
for k, v in e.attrib.items():
r[prefix + k] = v
# Add children
for c in e:
key = prefix + c.tag
# Scalar node (no children, has text)
if len(c) == 0 and c.text and c.text.strip():
r[key] = c.text.strip()
else:
# Nested node → recurse
r.update(flatten(c, key + "_"))
return r
# Parse XML
root = ET.parse(xml_file).getroot()
# Flatten all <Order> elements
rows = [flatten(order) for order in root.iter("Order")]
# Collect headers
headers = sorted({k for row in rows for k in row})
This snippet illustrates how to recursively flatten XML nodes and attributes into a structure suitable for Excel. For complex XML, this ensures that no data is lost and that each node maps to the correct column.
4.2 Generating XLSX Files from Parsed XML
Once the XML is parsed and flattened, the next step is writing the data into an Excel .xlsx file. Python libraries such as Free Spire.XLS for Python enable full spreadsheet creation without needing Excel installed, which is ideal for Linux servers or cloud environments.
Install Free Spire.XLS for Python:
pip install spire.xls.free
Steps for generating XLSX:
- Create a new workbook.
- Write headers and rows from the flattened data.
- Optionally, apply styles for better readability.
- Save the workbook as
.xlsx.
Python Example:
This example demonstrates how to generate an XLSX file from the parsed XML data.
from spire.xls import Workbook, BuiltInStyles
xlsx_output = "output/XMLToExcel1.xlsx"
wb = Workbook()
ws = wb.Worksheets.get_Item(0)
# Header row
for col, h in enumerate(headers, 1):
ws.Range.get_Item(1, col).Value = h
# Data rows
for row_idx, row in enumerate(rows, 2):
for col_idx, h in enumerate(headers, 1):
ws.Range.get_Item(row_idx, col_idx).Value = row.get(h, "")
# Apply styles (optional)
ws.AllocatedRange.Rows.get_Item(0).BuiltInStyle = BuiltInStyles.Heading2
for row in range(1, ws.AllocatedRange.Rows.Count):
if row % 2 == 0:
ws.AllocatedRange.Rows.get_Item(row).BuiltInStyle = BuiltInStyles.Accent2_20
else:
ws.AllocatedRange.Rows.get_Item(row).BuiltInStyle = BuiltInStyles.Accent2_40
# Save to XLSX
wb.SaveToFile(xlsx_output)
print("Done!")
After running the script, each XML node is flattened into rows, with columns representing attributes and child elements. This approach supports multiple worksheets, custom column names, and integration with further data transformations.
Below is the preview of the generated XLSX file:

For more examples of writing different types of data to Excel files using Python, see our Python write data to Excel guide.
4.3 Handling Complex XML
Business XML often contains irregular patterns. Using Python, you can:
- recursively flatten nested elements
- promote attributes into normal columns
- skip irrelevant elements
- create multiple sheets for hierarchical sections
- handle missing or optional fields by assigning defaults
The example above shows a single XML file; the same logic can be extended to handle complex structures without data loss.
If you are working with Office Open XML (OOXML) files, you can also directly load them and save as XLSX files using Free Spire.XLS for Python. Check out How to Convert OOXML to XLSX conversion with Python.
4.4 Batch Conversion
Python’s strength becomes especially clear when converting large folders of XML files. A script can:
- scan directories,
- parse each file using the same flattening logic,
- generate consistent XLSX files automatically.
This eliminates manual work and ensures reliable, error-free conversion across projects or datasets.
The following snippet illustrates a simple approach for batch converting multiple XML files to XLSX.
import os
input_dir = "xml_folder"
output_dir = "xlsx_folder"
for file_name in os.listdir(input_dir):
if file_name.endswith(".xml"):
xml_path = os.path.join(input_dir, file_name)
# Parse XML and generate XLSX (using previously defined logic)
convert_xml_to_xlsx(xml_path, output_dir)
5. Method 4: Custom Scripts or APIs for Enterprise Workflows
While the previous methods are suitable for one-time or batch conversions, enterprise environments often require automated, standardized, and scalable solutions for XML to XLSX conversion. Many business XML formats follow industry standards, involve complex schemas with mandatory and optional fields, and are integrated into broader data pipelines.
In these cases, companies typically develop custom scripts or API-based workflows to handle conversions reliably. For example:
- ERP or CRM exports: Daily XML exports containing invoices or orders are automatically converted to XLSX and fed into reporting dashboards.
- ETL pipelines: XML data from multiple systems is validated, normalized, and converted during Extract-Transform-Load processes.
- Cloud integration: Scripts or APIs run on cloud platforms (AWS Lambda, Azure Functions) to process large-scale XML files without manual intervention.
Key benefits of this approach include:
- Ensuring schema compliance through XSD validation.
- Maintaining consistent mapping rules across multiple systems.
- Automating conversions as part of regular business processes.
- Integrating seamlessly with cloud services and workflow automation platforms.
This workflow is ideal for scenarios where XML conversion is a recurring task, part of an enterprise reporting system, or required for compliance with industry data standards.
Tools like Spire.XLS for Python can also be integrated into these workflows to generate XLSX files programmatically on servers or cloud functions, enabling reliable, Excel-free conversion within automated enterprise pipelines.
6. Troubleshooting XML to XLSX Conversion
Depending on the method you choose—online tools, Excel, or Python—different issues may arise during XML conversion. Understanding these common problems helps ensure that your final XLSX file is complete and accurate.
Deeply Nested or Irregular XML
Nested structures may be difficult to flatten into a single sheet.
- Excel may require manual mapping or splitting into multiple sheets.
- Python allows recursive flattening or creating multiple sheets programmatically.
Missing or Optional Elements
Not all XML nodes appear in every record. Ensure column consistency by using blank cells for missing fields, rather than skipping them, to avoid misaligned data.
Attributes vs. Elements
Decide which attributes should become columns and which can remain internal.
- Excel may prompt for mapping.
- Python can extract all attributes flexibly using recursive parsing.
Encoding Errors
Incorrect character encoding can cause parsing failures.
- Ensure the XML declares encoding correctly (
UTF-8,UTF-16, etc.). - Python tip:
ET.parse(xml_file, parser=ET.XMLParser(encoding='utf-8'))helps handle encoding explicitly.
Large XML Files
Very large XML files may exceed browser or Excel limits.
- Online tools might fail or freeze.
- Excel may become unresponsive.
- Python can use streaming parsers like
iterparseto process large files with minimal memory usage.

Convert PDF Table to Word – Accurate & Reliable Methods
Table of Contents

Converting a PDF table to Word sounds simple, but anyone who has tried it knows the process can be surprisingly inconsistent. PDF files are designed primarily for display, not for structured editing, which often leads to corrupted table layouts when converting or copying. Users frequently encounter broken rows, merged columns, lost borders, inconsistent cell spacing, or tables being exported as images rather than editable Word tables.
This complete guide explains reliable methods to convert PDF tables to Word tables. You will learn online tools, manual approaches, and highly accurate programmatic solutions. If you need to convert PDF tables to Word, extract structured data from PDF, or produce fully editable Word tables for professional or automated workflows, this article provides the practical knowledge and technical insights you need.
1. Why Converting PDF Tables to Word Is Difficult
Before exploring conversion methods, it’s important to understand why tables in PDFs are difficult to interpret. This helps you select the right tool depending on layout complexity.
1.1 PDFs Do Not Contain Real Tables
Unlike Word or HTML, PDF files do not store table structures. Instead, they store:
- text using absolute positions
- lines and borders as drawing paths
- rows/columns only as visual alignment, not structured grid data
As a result:
- Rows and columns are not recognized as cells
- Line elements may not correspond to actual table boundaries
- Choosing text or copying often disrupts the layout
This is why simple copy-paste almost always fails.
1.2 Word Requires Structured Table Elements
Microsoft Word expects:
- a defined
<table>element - consistent row/column counts
- true cell boundaries
- adjustable column widths
If the PDF content cannot be interpreted into this structure, Word creates unpredictable results—or exports the table as an image.
Understanding these limitations clarifies why reliable PDF table extraction requires intelligent parsing beyond simple visual detection.
2. Overview of Reliable Methods
This guide covers three practical ways to convert PDF tables into Word tables:
- Online PDF-to-Word converters – fastest, minimal control
- Desktop software – more stable, better accuracy
- Programmatic extraction and table reconstruction – highest precision and fully editable results
Tip: Most non-programmatic solutions convert the entire PDF into a Word file. If you only need the tables, you may need to manually remove the surrounding content afterward.
The most accurate method is extracting table data programmatically and rebuilding the Word table—this avoids formatting losses and ensures fully editable, clean table output.

Before using the following methods, install the required components.
Required Packages
Free Spire.Doc for Python – handles PDF export
pip install spire.doc.free
Pygments – generates syntax-highlighted HTML
pip install pygments
3.1 Method A: Direct Text-to-PDF (No Syntax Highlighting)
This method reads the .py file as plain text and writes it into a PDF. It is suitable for simple exports, documentation snapshots, and internal archiving, which may not require syntax highlighting.
Example Code
from spire.doc import Document, FileFormat, BreakType, Color, LineSpacingRule, LineNumberingRestartMode, TextRange
# Read the Python code as a string
with open("Python.py", "r", encoding="utf-8") as f:
python_code = f.read()
# Create a new document
doc = Document()
# Add the Python code to the document
section = doc.AddSection()
paragraph = section.AddParagraph()
for line_number, line in enumerate(python_code.split("\n")):
tr = paragraph.AppendText(line)
# Set the character format
tr.CharacterFormat.FontName = "Consolas"
tr.CharacterFormat.FontSize = 10.0
if line_number < len(python_code.split("\n")) - 1:
paragraph.AppendBreak(BreakType.LineBreak)
# Optional settings
# Set the background color and line spacing
paragraph.Format.BackColor = Color.get_LightGray()
paragraph.Format.LineSpacingRule = LineSpacingRule.Multiple
paragraph.Format.LineSpacing = 12.0 # 12pt meaning single spacing
# Set the line numbering
section.PageSetup.LineNumberingStartValue = 1
section.PageSetup.LineNumberingStep = 1
section.PageSetup.LineNumberingRestartMode = LineNumberingRestartMode.RestartPage
section.PageSetup.LineNumberingDistanceFromText = 10.0
# Save the document to a PDF file
doc.SaveToFile("output/Python-PDF.docx", FileFormat.Docx)
doc.SaveToFile("output/Python-PDF.pdf", FileFormat.PDF)
How It Works
This method inserts the Python code line by line using AppendText(), adds line breaks with AppendBreak(), and exports the final document through SaveToFile().
Below is the output effect after applying this method:

For more details on customizing and inserting text into a PDF document, see our guide on Appending Text to PDF Documents with Python.
3.2 Method B: Syntax-Highlighted PDF (HTML → PDF)
When producing tutorials or readable documentation, syntax highlighting helps distinguish keywords and improves overall clarity. This method uses Pygments to generate inline-styled HTML, then inserts the HTML into a document.
Example Code
from spire.doc import Document, FileFormat, ParagraphStyle, IParagraphStyle
from pygments import highlight
from pygments.lexers import PythonLexer
from pygments.formatters import HtmlFormatter
def py_to_inline_html(py_file_path):
with open(py_file_path, "r", encoding="utf-8") as f:
code = f.read()
formatter = HtmlFormatter(noclasses=True, linenostart=1, linenos='inline') # Line numbers are optional
inline_html = highlight(code, PythonLexer(), formatter)
return inline_html
html_result = py_to_inline_html("Python.py")
doc = Document()
section = doc.AddSection()
paragraph = section.AddParagraph()
# Insert formatted HTML
paragraph.AppendHTML(html_result)
doc.SaveToFile("output/Python-PDF-Highlighted.pdf", FileFormat.PDF)
How It Works
Pygments first formats the code as inline CSS-based HTML. The HTML is added through AppendHTML(), and the completed document is exported using SaveToFile().
Below is the visual result generated by this styled HTML method:

3.3 Batch Conversion (Folder-to-PDF Workflows)
For converting multiple .py files at once, you only need a short loop to process all files in a directory and save them as PDFs.
Example Code (Minimal Batch Processing)
import os
input_folder = "scripts"
output_folder = "pdf-output"
os.makedirs(output_folder, exist_ok=True)
for file in os.listdir(input_folder):
if file.endswith(".py"):
py_path = os.path.join(input_folder, file)
pdf_path = os.path.join(output_folder, file.replace(".py", ".pdf"))
# Call your chosen conversion function here
convert_py_to_pdf(py_path, pdf_path)
Notes
- Reuses the conversion function defined earlier.
- Automatically saves each .py file as a PDF with the same filename.
- Works for both plain-text and syntax-highlighted methods.

C# Save Excel File — Save Excel to XLSX, PDF & More
Table of Contents

Saving Excel files in C# is a common task in many .NET applications, especially when generating reports, exporting analytical data, or automating system logs. Whether you’re working with financial summaries or daily operations data, being able to create and save Excel files programmatically can significantly improve efficiency and accuracy.
In C#, developers can handle Excel files in multiple ways—creating new workbooks, writing data, and saving them in various formats such as XLSX, CSV, or PDF. With the help of dedicated Excel libraries, these operations can be automated efficiently without relying on Microsoft Excel or manual intervention.
In this article, we will explore how to:
- Prepare your development environment
- Save DataTable or DataGridView data to Excel
- Save Excel files in different spreadsheet formats (CSV, XLS, etc.)
- Export Excel files to document formats (PDF, HTML, etc.)
- Save Excel workbooks to a MemoryStream for web apps
- Open and re-save existing Excel files
Prepare the Development Environment
Before diving into code, set up your development environment with an Excel library that supports creating, reading, and saving files in .NET. In this tutorial, we’ll use Free Spire.XLS for .NET.
Step 1: Install Spire.XLS via NuGet
Install-Package FreeSpire.XLS
Step 2: Import the Required Namespace
using Spire.Xls;
Step 3: Create, Write, and Save a Simple Excel File
// Create a new workbook and get the first worksheet
Workbook workbook = new Workbook();
Worksheet sheet = workbook.Worksheets[0];
// Write "Hello World!" into cell A1
sheet.Range["A1"].Text = "Hello World!";
// Save the workbook to a file
workbook.SaveToFile("HelloWorld.xlsx", ExcelVersion.Version2016);
This simple example shows the basic workflow: creating a workbook, writing data into a cell, and saving the file.
After this, you can explore key classes and methods such as:
- Workbook – represents the entire Excel file.
- Worksheet – represents a single sheet within the workbook.
- Range – allows access to specific cells for input, formatting, or styling.
- Workbook.SaveToFile() – saves the workbook to disk in the specified Excel format.
Save Data to an Excel File in C#
Saving structured data like DataTable or DataGridView into an Excel file is one of the most practical tasks in C# development. Whether your application produces database results, UI grid content, or automated reports, exporting these datasets into Excel provides better readability and compatibility.
Example 1: Save DataTable to Excel
using Spire.Xls;
using System.Data;
Workbook workbook = new Workbook();
Worksheet sheet = workbook.Worksheets[0];
sheet.Name = "EmployeeData";
DataTable table = new DataTable();
table.Columns.Add("EmployeeID");
table.Columns.Add("FullName");
table.Columns.Add("Department");
table.Columns.Add("HireDate");
table.Columns.Add("Salary");
// Add sample rows
table.Rows.Add("E001", "Alice Johnson", "Finance", "2020-03-12", "7500");
table.Rows.Add("E002", "Bob Williams", "Human Resources", "2019-08-05", "6800");
table.Rows.Add("E003", "Catherine Lee", "IT", "2021-01-20", "8200");
table.Rows.Add("E004", "David Smith", "Marketing", "2018-11-30", "7100");
table.Rows.Add("E005", "Emily Davis", "Sales", "2022-06-15", "6900");
// Insert the DataTable into worksheet
sheet.InsertDataTable(table, true, 1, 1);
// Apply built-in formats
sheet.AllocatedRange.Rows[0].BuiltInStyle = BuiltInStyles.Heading1;
for (int i = 1; i < sheet.AllocatedRange.Rows.Count(); i++)
{
sheet.AllocatedRange.Rows[i].BuiltInStyle = BuiltInStyles.Accent1;
}
sheet.AllocatedRange.AutoFitColumns();
sheet.AllocatedRange.AutoFitRows();
// Save to Excel
workbook.SaveToFile("EmployeeDataExport.xlsx", FileFormat.Version2016);
How it works:
- InsertDataTable() inserts data starting from a specific cell.
- The true argument includes column headers.
- SaveToFile() saves the workbook to disk; the second parameter specifies the Excel format version.
- FileFormat.Version2016 specifies the Excel format version.
Below is a sample output showing how the exported DataTable looks in Excel:

Example 2: Save DataGridView to Excel
Workbook workbook = new Workbook();
Worksheet sheet = workbook.Worksheets[0];
sheet.InsertDataTable(((DataTable)dataGridView1.DataSource), true, 1, 1);
workbook.SaveToFile("GridViewExport.xlsx", FileFormat.Version2016);
Tip: Before saving, ensure that your DataGridView’s data source is properly cast to a DataTable.This ensures the exported structure matches the UI grid layout.
If you want learn how to create Excel files with more data types, formatting, and other elements, you can explore the article How to Create Excel Files in C#.
Save Excel File as CSV or XLS in C#
Different systems and platforms require different spreadsheet formats. While XLSX is now the standard, CSV, XLS, and other formats remain common in enterprise environments. Exporting to different formats allows Excel data to be shared, processed, or imported by various applications.
Example 1: Save Excel as CSV
CSV (Comma-Separated Values) is a simple text-based format ideal for exchanging data with databases, web applications, or other systems that support plain text files.
Workbook workbook = new Workbook();
workbook.LoadFromFile("EmployeeDataExport.xlsx");
workbook.SaveToFile("Report.csv", ",", FileFormat.CSV);
Example 2: Save Excel as XLS (Legacy Format)
XLS (Excel 97–2003 format) is a legacy binary format still used in older systems or applications that do not support XLSX. Saving to XLS ensures compatibility with legacy enterprise workflows.
Workbook workbook = new Workbook();
workbook.LoadFromFile("EmployeeDataExport.xlsx");
workbook.SaveToFile("Report_legacy.xls", ExcelVersion.Version97to2003);
Additional Supported Spreadsheet Formats
In addition to the commonly used CSV, XLS, and XLSX formats, the library also supports several other spreadsheet and template formats. The table below lists these formats together with their corresponding FileFormat enumeration values for easy reference when saving files programmatically.
| Format | Description | Corresponding Enum (FileFormat) |
|---|---|---|
| ODS | OpenDocument Spreadsheet | FileFormat.ODS |
| XLSM | Macro-enabled Excel workbook | FileFormat.Xlsm |
| XLSB | Binary Excel workbook | FileFormat.Xlsb2007 / FileFormat.Xlsb2010 |
| XLT | Excel 97–2003 template | FileFormat.XLT |
| XLTX | Excel Open XML template | FileFormat.XLTX |
| XLTM | Macro-enabled Excel template | FileFormat.XLTM |
These additional formats are useful for organizations that work with legacy systems, open document standards, or macro/template–based automation workflows.
Save Excel as PDF or HTML in C#
In many cases, Excel files need to be converted into document or web formats for easier publishing, printing, or sharing.
Exporting to PDF is ideal for fixed-layout reports and printing, while HTML is suitable for viewing Excel data in a web browser.
Example 1: Save Excel as PDF
The following example shows how to save an Excel workbook as a PDF file using C#. This is useful for generating reports that preserve layout and formatting.
Workbook workbook = new Workbook();
workbook.LoadFromFile("EmployeeDataExport.xlsx");
workbook.SaveToFile("EmployeeDataExport.pdf", FileFormat.PDF);
Here is an example of the generated PDF file after exporting from Excel:

Example 2: Save Excel as HTML
This example demonstrates how to save an Excel workbook as an HTML file, making it easy to render the data in a web browser or integrate with web applications.
Workbook workbook = new Workbook();
workbook.LoadFromFile("EmployeeDataExport.xlsx");
workbook.SaveToFile("EmployeeDataExport.html", FileFormat.HTML);
Below is a preview of the exported HTML file rendered in a browser:

Additional Supported Document & Web Formats
In addition to PDF and HTML, the library supports several other document and web-friendly formats. The table below shows these formats together with their FileFormat enumeration values for easy reference.
| Format | Description | Corresponding Enum (FileFormat) |
|---|---|---|
| XML | Excel data exported as XML | FileFormat.XML |

These formats provide additional flexibility for distributing Excel content across different platforms and workflows, whether for printing, web publishing, or automation.
Save an Excel File to MemoryStream in C#
In web applications or cloud services, saving Excel files directly to disk may not be ideal due to security or performance reasons. Using MemoryStream allows you to generate Excel files in memory and deliver them directly to clients for download. Spire.XLS for .NET also supports both loading and saving workbooks through MemoryStream, making it easy to handle Excel files entirely in memory.
Workbook workbook = new Workbook();
Worksheet sheet = workbook.Worksheets[0];
sheet.Range["A1"].Text = "Export to Stream";
using (MemoryStream stream = new MemoryStream())
{
workbook.SaveToStream(stream, ExcelVersion.Version2016);
byte[] bytes = stream.ToArray();
// Example: send bytes to client for download in ASP.NET
// Response.BinaryWrite(bytes);
}
This approach is particularly useful for ASP.NET, Web API, or cloud services, where you want to serve Excel files dynamically without creating temporary files on the server.
Open and Re-Save Excel Files in C#
In many applications, you may need to load an existing Excel workbook, apply updates or modifications, and then save it back to disk or convert it to a different format. This is common when updating reports, modifying exported data, or automating Excel file workflows.
Example: Open and Update an Excel File
The following C# code loads the previous workbook, updates the first cell, and saves the changes:
Workbook workbook = new Workbook();
workbook.LoadFromFile("EmployeeDataExport.xlsx");
Worksheet sheet = workbook.Worksheets[0];
sheet.Range["A1"].Text = "Updated Content"; // Update the cell value
sheet.Range["A1"].AutoFitColumns(); // Autofit the column width
// Save the updated workbook
workbook.Save(); // Saves to original file
workbook.SaveToFile("UpdatedCopy.xlsx", ExcelVersion.Version2016); // Save as new file
The screenshot below shows the updated Excel sheet after modifying and saving the file:

PowerPoint presentations are perfect for visual storytelling, but sometimes you need a Word version of your slides — for documentation, editing, or printing handouts. Converting PowerPoint (PPT/PPTX) to Word allows you to reuse your slides as editable text, add annotations, and integrate them into larger written materials such as reports or manuals.
This tutorial walks you through three practical ways to convert PowerPoint to Word, depending on your tools and workflow:
- Using PowerPoint’s built-in Export feature — quick and simple, no extra software needed
- Using free online PowerPoint-to-Word converters — accessible from any browser
- Using Python automation — ideal for batch processing and professional environments
Let’s look at how each method works and which one suits your needs best.
Method 1: Convert PowerPoint to Word Using Microsoft Office
If you already have Microsoft PowerPoint and Word installed, you can convert presentations to Word directly without extra tools. There are two approaches:
- "Create Handouts" (useful for printable slide notes but not editable slides)
- "Save as PDF and open in Word" (recommended for fully editable documents)
Let’s look at both.
1.1 Convert PowerPoint to Word Using "Create Handouts"
This built-in PowerPoint feature exports slides into Word for creating lecture notes or handouts.
Steps:
- Open your PowerPoint file.
- Go to File → Export → Create Handouts.
- Choose a layout option (e.g., Notes below slides, Blank lines, Outline only).
- Click OK to generate a Word file.

However, the exported slides appear in Word as static images, not editable objects. You can edit text around them — for example, adding notes, comments, or descriptions — but not the content inside the slides.
So this method is great for printing or distributing summaries, but not ideal for editing slide content.
If you want to directly export the slides as static images, you can check out how to export PowerPoint slides as images for a dedicated approach.
1.2 Convert PowerPoint to Editable Word via PDF
For a fully editable conversion, the most effective approach is to first save your presentation as a PDF, then open it in Microsoft Word.
Steps:
-
In PowerPoint:
- Go to File → Save As → PDF.
- Choose output location and click Save.

-
In Word:
- Open Microsoft Word.
- Click File → Open, and select the PDF you just created.
- Click Yes in the pop-up window, and Word will automatically convert the PDF into an editable Word document.

You can now edit the document as you wish or save it as a .docx file.
Why This Works Better:
- PowerPoint exports the slides to PDF with accurate layout and vector graphics.
- Word’s built-in PDF conversion engine can reconstruct text boxes, images, and formatting into editable Word objects.
- The resulting document maintains both visual fidelity and text accessibility, allowing you to edit everything directly.
Tips for Better Results:
- Use a high-resolution PDF export for clean images.
- Avoid overly complex transitions or 3D effects — they’ll appear as flat visuals.
- After conversion, recheck font styles and paragraph spacing.
This PowerPoint → PDF → Word workflow provides the best balance between appearance and editability — ideal for documentation, publishing, and archiving.
Method 2: Convert PowerPoint to Word Using Online Tools
If you don’t have Office installed, online PowerPoint-to-Word converters can help. They’re fast, accessible, and platform-independent.
Why Choose an Online Converter
- Works directly in your browser — no installation needed.
- Compatible with all systems (Windows, macOS, Linux, ChromeOS).
- Convenient for occasional users or lightweight tasks.
However, keep in mind:
- Many tools have file size or page count limits.
- Uploading confidential files to third-party servers poses privacy risks.
Recommended Free Tools
| Tool | File Size Limit | Output Format | Registration | Batch Support |
|---|---|---|---|---|
| FreeConvert | 1024MB | DOCX/DOC | Optional | Yes |
| Zamzar | 7MB | DOCX/DOC | Optional | Yes |
| Convertio | 100MB | DOCX/DOC | Optional | Yes |
Note: Always read each site’s privacy policy before uploading sensitive material.
Example: Using FreeConvert
- Visit FreeConvert PPT to Word Converter.
- Upload your PowerPoint file and click Convert.
- Wait for the conversion to complete.
- Download the converted Word document.

Advantages:
- No software installation
- Simple drag-and-drop interface
- Good formatting accuracy
Drawbacks:
- Limited free conversions per day
- May compress or reformat images slightly
Online converters are convenient for quick one-off tasks, but for regular or large-scale conversions, a desktop or automated solution is more efficient.

Method 3: Automate PowerPoint to Word Conversion with Python
For developers or teams who need to handle presentations in bulk, automation offers the fastest and most reliable solution. With just a few lines of Python code, you can convert multiple PowerPoint presentations into Word documents — all processed locally on your machine, with no file size limits or privacy concerns.
This example uses Free Spire.Office for Python, an all-in-one library that makes it possible to complete the entire conversion with a single toolkit.
Install the library with pip:
pip install spire.office.free
Example: Convert PowerPoint to Word in Python
import os
from spire.presentation import Presentation, FileFormat
from spire.pdf import PdfDocument, FileFormat as PdfFileFormat
input_ppt = "G:/Documents/Sample14.pptx"
temp_pdf = "output/temp.pdf"
output_docx = "output/output.docx"
# Step 1: Convert PowerPoint to PDF
presentation = Presentation()
presentation.LoadFromFile(input_ppt)
presentation.SaveToFile(temp_pdf, FileFormat.PDF)
# Step 2: Convert PDF to Word
pdf = PdfDocument()
pdf.LoadFromFile(temp_pdf)
pdf.SaveToFile(output_docx, PdfFileFormat.DOCX)
# Step 3: Delete the temporary PDF file
if os.path.exists(temp_pdf):
os.remove(temp_pdf)
print("PPTX has been successfully converted to Word!")
The image below shows the result of converting a PowerPoint presentation to a Word document using Python.

Code Explanation
This script uses Free Spire.Office for Python to handle both steps of the conversion:
- Spire.Presentation loads the PowerPoint file and exports it as a high-quality PDF.
- Spire.PDF converts the PDF into a fully editable Word document (.docx).
- After conversion, the temporary PDF file is deleted automatically to keep your workspace clean.
This workflow is fast, reliable, and keeps all files local — ensuring consistent formatting, accurate layout, and editable text without using any online services.
Batch Conversion Example
You can extend the same logic to convert all PowerPoint files in a folder:
import os
from spire.presentation import Presentation, FileFormat
from spire.pdf import PdfDocument, FileFormat as PdfFileFormat
folder = "presentations"
for file in os.listdir(folder):
if file.endswith(".pptx"):
ppt_path = os.path.join(folder, file)
temp_pdf = os.path.join(folder, file.replace(".pptx", ".pdf"))
docx_path = os.path.join(folder, file.replace(".pptx", ".docx"))
# Step 1: Convert PPTX to PDF
presentation = Presentation()
presentation.LoadFromFile(ppt_path)
presentation.SaveToFile(temp_pdf, FileFormat.PDF)
# Step 2: Convert PDF to Word
pdf = PdfDocument()
pdf.LoadFromFile(temp_pdf)
pdf.SaveToFile(docx_path, PdfFileFormat.DOCX)
# Step 3: Delete the temporary PDF file
if os.path.exists(temp_pdf):
os.remove(temp_pdf)
print("All PowerPoint files have been successfully converted to Word!")
This approach is perfect for corporate archives, educational content libraries, or automated reporting systems, allowing dozens or hundreds of presentations to be converted quickly and securely, with no leftover temporary files.

Common Questions on Converting PowerPoint to Word
Q1: Can I convert PowerPoint to Word without losing formatting?
Yes. The PDF → Word approach preserves text boxes, layouts, and images with high accuracy.
Q2: Why can’t I edit slides when using "Create Handouts"?
Because PowerPoint exports slides as static images. You can edit notes or surrounding text, but not the slide content itself.
Q3: Is there a way to keep animations in Word?
No, Word doesn’t support animation effects — only static content is transferred.
Q4: How do I convert multiple PowerPoint files automatically?
Use the Python automation method shown above. It can process all .pptx files in a folder programmatically.
Q5: Which method gives the most professional-looking result?
The Online Tools and the Python automation method generally provide the best balance between layout fidelity and editability.
