Batch Conversion of Multiple HTML Files to Word in Java

Sometimes you may need to convert hundreds of HTML files into Word documents. Here’s how to batch process them in Java.

import com.spire.doc.Document;
import com.spire.doc.FileFormat;
import com.spire.doc.documents.XHTMLValidationType;
import java.io.File;

public class BatchConvertHtmlToWord {
    public static void main(String[] args) {
        File folder = new File("C:\\Users\\Administrator\\Desktop\\HtmlFiles");

        for (File file : folder.listFiles()) {
            if (file.getName().endsWith(".html") || file.getName().endsWith(".htm")) {
                Document document = new Document();
                document.loadFromFile(file.getAbsolutePath(), FileFormat.Html, XHTMLValidationType.None);

                String outputPath = "output/" + file.getName().replace(".html", ".docx");
                document.saveToFile(outputPath, FileFormat.Docx);
                document.dispose();

                System.out.println(file.getName() + " converted to Word!");
            }
        }
    }
}

This approach is great for reporting systems where multiple HTML reports are generated daily.

Best Practices for HTML to Word Conversion

• Use Inline CSS for Reliable Styling
  Inline CSS ensures that fonts, colors, and spacing are preserved during conversion. External stylesheets may not always render correctly, especially if they are not accessible at runtime.
• Validate HTML Structure
  Well-formed HTML with proper nesting and closed tags helps render tables, lists, and headings accurately.
• Optimize Images
  Use absolute URLs or embed images as base64. Resize large images to fit Word layouts and reduce file size.
• Manage Resources in Batch Conversion
  When processing multiple files, convert them one by one and call dispose() after each document to prevent memory issues.
• Preserve Page Layouts
  Set page margins, orientation, and paper size to ensure the Word document looks professional, especially for reports and formal documents.

Why Choose Spire.Doc for Python to Align Text?​

Before diving into code, let’s clarify why Spire.Doc is a top choice for text alignment tasks:​

• Full Alignment Support: Natively supports all standard alignment types (Left, Right, Center, Justify) for paragraphs.​
• No Microsoft Word Dependency: Runs independently - no need to install Word on your machine.​
• High Compatibility: Works with .docx, .doc, and other Word formats, ensuring your aligned documents open correctly across devices.​
• Fine-Grained Control: Adjust alignment for entire paragraphs or table cells.​

Core Text Alignment Types in Spire.Doc​

Spire.Doc uses the HorizontalAlignment enum to define text alignment. The most common values are:​

• HorizontalAlignment.Left: Aligns text to the left margin (default).​
• HorizontalAlignment.Right: Aligns text to the right margin.​
• HorizontalAlignment.Center: Centers text horizontally between margins.​
• HorizontalAlignment.Justify: Adjusts text spacing so both left and right edges align with margins.​
• HorizontalAlignment.Distribute: Adjusts character spacing (adds space between letters) and word spacing to fill the line.

Below, we’ll cover how to programmatically set paragraph alignment (left, right, center, justified, and distributed) in Word using Python

Step-by-Step: Align Text in Word in Python

Here are the actionable steps to generate a Word document with 5 paragraphs, each using a different alignment style.

Step 1: Install Spire.Doc for Python

Open your terminal/command prompt​, and then run the following command to install the latest version:

pip install Spire.Doc

Step 2: Import Required Modules

Import the core classes from Spire.Doc. These modules let you create documents, sections, paragraphs, and configure formatting:

from spire.doc import *
from spire.doc.common import *

Step 3: Create a New Word Document

Initialize a Document instance that represents your empty Word file:

# Create a Document instance
doc = Document()

Step 4: Add a Section to the Document

Word documents organize content into sections (each section can have its own margins, page size, etc.). We’ll add one section to hold our paragraphs:

# Add a section to the document
section = doc.AddSection()

Step 5: Add Paragraphs with Different Alignments

A section contains paragraphs, and each paragraph’s alignment is controlled via the HorizontalAlignment enum. We’ll create 5 paragraphs, one for each alignment type.

1. Left Align in Python

Left alignment is the default for most text (text aligns to the left margin).

# Left aligned text
paragraph1 = section.AddParagraph()
paragraph1.AppendText("This is left-aligned text.")
paragraph1.Format.HorizontalAlignment = HorizontalAlignment.Left

2. Right Align Text in Python

Right alignment is useful for dates, signatures, or page numbers (text aligns to the right margin).

# Right aligned text
paragraph2 = section.AddParagraph()
paragraph2.AppendText("This is right-aligned text.")
paragraph2.Format.HorizontalAlignment = HorizontalAlignment.Right

3. Center Text in Python

Center alignment works well for titles or headings (text centers between left and right margins). Use to center text in Python:

# Center aligned text
paragraph3 = section.AddParagraph()
paragraph3.AppendText("This is center-aligned text.")
paragraph3.Format.HorizontalAlignment = HorizontalAlignment.Center

4. Justify Text in Python

Justified text aligns both left and right margins (spaces between words are adjusted for consistency). Ideal for formal documents like essays or reports.

# Justified
paragraph4 = section.AddParagraph()
paragraph4.AppendText("This is justified text.")
paragraph4.Format.HorizontalAlignment = HorizontalAlignment.Justify

Note: Justified alignment is more visible with longer text - short phrases may not show the spacing adjustment.

5. Distribute Text in Python

Distributed alignment is similar to justified, but evenly distributes single-line text (e.g., unevenly spaced words or short phrases).

# Distributed
Paragraph5 = section.AddParagraph()
Paragraph5.AppendText("This is evenly distributed text.")
Paragraph5.Format.HorizontalAlignment = HorizontalAlignment.Distribute

Step 6: Save and Close the Document

Finally, save the document to a specified path and close the Document instance to free resources:

# Save the document
document.SaveToFile("TextAlignment.docx", FileFormat.Docx2016)
# Close the document to release memory
document.Close()

Output:

Pro Tip: Spire.Doc for Python also provides interfaces to align tables in Word or align text in table cells.

FAQs About Python Text Alignment

Q1: Is Spire.Doc for Python free?

A: Spire.Doc offers a free version with limitations. For full functionality, you can request a 30-day trial license here.

Q2: Can I set text alignment for existing Word documents

A: Yes. Spire.Doc lets you load existing documents and modify text alignment for specific paragraphs. Here’s a quick example:

from spire.doc import *

# Load an existing document
doc = Document()
doc.LoadFromFile("ExistingDocument.docx")

# Get the first section and first paragraph
section = doc.Sections[0]
paragraph = section.Paragraphs[0]

# Change alignment to center
paragraph.Format.HorizontalAlignment = HorizontalAlignment.Center

# Save the modified document
doc.SaveToFile("UpdatedDocument.docx", FileFormat.Docx2016)
doc.Close()

Q3: Can I apply different alignments to different parts of the same paragraph?

A: No. Text alignment is a paragraph-level setting in Word, not a character-level setting. This means all text within a single paragraph must share the same alignment (left, right, center, etc.).

If you need mixed alignment in the same line, you’ll need to use a table with invisible borders.

Q4: Can Spire.Doc for Python handle other text formatting?

A: Absolutely! Spire.Doc lets you combine alignment with other formatting like fonts, line spacing, bullet points, and more.

Conclusion

Automating Word text alignment with Python and Spire.Doc saves time, reduces human error, and ensures consistency across documents. The code example provided offers a clear template for implementing left, right, center, justified, and distributed alignment, and adapting it to your needs is as simple as modifying the text or adding more formatting rules.

Try experimenting with different alignment combinations, and explore Spire.Doc’s online documentation to unlock more formatting possibilities.

PM> Install-Package Spire.Doc

This installation adds the necessary references, enabling you to programmatically work with Word documents.

Load Word Document (.doc/.docx) in C#

To begin, you need to load a Word document into your project. The following example demonstrates how to load a .docx or .doc file in C#:

using Spire.Doc;
using Spire.Doc.Documents;
using System;

namespace LoadWordExample
{
    class Program
    {
        static void Main(string[] args)
        {
            // Specify the path of the Word document
            string filePath = @"C:\Documents\Sample.docx";

            // Create a Document object
            using (Document document = new Document())
            {
                // Load the Word .docx or .doc document
                document.LoadFromFile(filePath);
            }
        }
    }
}

This code loads a Word file from the specified path into a Document object, which is the entry point for accessing all document elements.

Read and Extract Content from Word Document in C#

After loading the Word document into a Document object, you can access its contents programmatically. This section covers various methods for extracting different types of content effectively.

Extract Text

Extracting text is often the first step in reading Word documents. You can retrieve all text content using the built-in GetText() method:

using (StreamWriter writer = new StreamWriter("ExtractedText.txt", false, Encoding.UTF8))
{
    // Get all text from the document
    string allText = document.GetText();
    
    // Write the entire text to a file
    writer.Write(allText);
}

This method extracts all text, disregarding formatting and non-text elements like images.

Read Paragraphs and Formatting Information

When working with Word documents, it is often useful not only to access the text content of paragraphs but also to understand how each paragraph is formatted. This includes details such as alignment and spacing after the paragraph, which can affect layout and readability.

The following example demonstrates how to iterate through all paragraphs in a Word document and retrieve their text content and paragraph-level formatting in C#:

using (StreamWriter writer = new StreamWriter("Paragraphs.txt", false, Encoding.UTF8))
{
    // Loop through all sections
    foreach (Section section in document.Sections)
    {
        // Loop through all paragraphs in the section
        foreach (Paragraph paragraph in section.Paragraphs)
        {
            // Get paragraph alignment
            HorizontalAlignment alignment = paragraph.Format.HorizontalAlignment;

            // Get spacing after paragraph
            float afterSpacing = paragraph.Format.AfterSpacing;

            // Write paragraph formatting and text to the file
            writer.WriteLine($"[Alignment: {alignment}, AfterSpacing: {afterSpacing}]");
            writer.WriteLine(paragraph.Text);
            writer.WriteLine(); // Add empty line between paragraphs
        }
    }
}

This approach allows you to extract both the text and key paragraph formatting attributes, which can be useful for tasks such as document analysis, conditional processing, or preserving layout when exporting content.

Extract Images

Images embedded within Word documents play a vital role in conveying information. To extract these images, you will examine each paragraph's content, identify images (typically represented as DocPicture objects), and save them for further use:

// Create the folder if it does not exist
string imageFolder = "ExtractedImages";
if (!Directory.Exists(imageFolder))
    Directory.CreateDirectory(imageFolder);

int imageIndex = 1;

// Loop through sections and paragraphs to find images
foreach (Section section in document.Sections)
{
    foreach (Paragraph paragraph in section.Paragraphs)
    {
        foreach (DocumentObject obj in paragraph.ChildObjects)
        {
            if (obj is DocPicture picture)
            {
                // Save each image as a separate PNG file
                string fileName = Path.Combine(imageFolder, $"Image_{imageIndex}.png");
                picture.Image.Save(fileName, System.Drawing.Imaging.ImageFormat.Png);
                imageIndex++;
            }
        }
    }
}

This code saves all images in the document as separate PNG files, with options to choose other formats like JPEG or BMP.

Extract Table Data

Tables are commonly used to organize structured data, such as financial reports or survey results. To access this data, iterate through the tables in each section and retrieve the content of individual cells:

// Create a folder to store tables
string tableDir = "Tables";
if (!Directory.Exists(tableDir))
    Directory.CreateDirectory(tableDir);

// Loop through each section
for (int sectionIndex = 0; sectionIndex < document.Sections.Count; sectionIndex++)
{
    Section section = document.Sections[sectionIndex];
    TableCollection tables = section.Tables;

    // Loop through all tables in the section
    for (int tableIndex = 0; tableIndex < tables.Count; tableIndex++)
    {
        ITable table = tables[tableIndex];
        string fileName = Path.Combine(tableDir, $"Section{sectionIndex + 1}_Table{tableIndex + 1}.txt");

        using (StreamWriter writer = new StreamWriter(fileName, false, Encoding.UTF8))
        {
            // Loop through each row
            for (int rowIndex = 0; rowIndex < table.Rows.Count; rowIndex++)
            {
                TableRow row = table.Rows[rowIndex];

                // Loop through each cell
                for (int cellIndex = 0; cellIndex < row.Cells.Count; cellIndex++)
                {
                    TableCell cell = row.Cells[cellIndex];

                    // Loop through each paragraph in the cell
                    for (int paraIndex = 0; paraIndex < cell.Paragraphs.Count; paraIndex++)
                    {
                        writer.Write(cell.Paragraphs[paraIndex].Text.Trim() + " ");
                    }

                    // Add tab between cells
                    if (cellIndex < row.Cells.Count - 1) writer.Write("\t");
                }

                // Add newline after each row
                writer.WriteLine();
            }
        }
    }
}

This method allows efficient extraction of structured data, making it ideal for generating reports or integrating content into databases.

Read Comments

Comments are valuable for collaboration and feedback within documents. Extracting them is crucial for auditing and understanding the document's revision history.

The Document object provides a Comments collection, which allows you to access all comments in a Word document. Each comment contains one or more paragraphs, and you can extract their text for further processing or save them into a file.

using (StreamWriter writer = new StreamWriter("Comments.txt", false, Encoding.UTF8))
{
    // Loop through all comments in the document
    foreach (Comment comment in document.Comments)
    {
        // Loop through each paragraph in the comment
        foreach (Paragraph p in comment.Body.Paragraphs)
        {
            writer.WriteLine(p.Text);
        }
        // Add empty line to separate different comments
        writer.WriteLine();
    }
}

This code retrieves the content of all comments and outputs it into a single text file.

Retrieve Document Metadata

Word documents contain metadata such as the title, author, and subject. These metadata items are stored as document properties, which can be accessed through the BuiltinDocumentProperties property of the Document object:

using (StreamWriter writer = new StreamWriter("Metadata.txt", false, Encoding.UTF8))
{
    // Write built-in document properties to file
    writer.WriteLine("Title: " + document.BuiltinDocumentProperties.Title);
    writer.WriteLine("Author: " + document.BuiltinDocumentProperties.Author);
    writer.WriteLine("Subject: " + document.BuiltinDocumentProperties.Subject);
}

Read Headers and Footers

Headers and footers frequently contain essential content like page numbers and titles. To programmatically access this information, iterate through each section's header and footer paragraphs and retrieve the text of each paragraph:

using (StreamWriter writer = new StreamWriter("HeadersFooters.txt", false, Encoding.UTF8))
{
    // Loop through all sections
    foreach (Section section in document.Sections)
    {
        // Write header paragraphs
        foreach (Paragraph headerParagraph in section.HeadersFooters.Header.Paragraphs)
        {
            writer.WriteLine("Header: " + headerParagraph.Text);
        }

        // Write footer paragraphs
        foreach (Paragraph footerParagraph in section.HeadersFooters.Footer.Paragraphs)
        {
            writer.WriteLine("Footer: " + footerParagraph.Text);
        }
    }
}

This method ensures that all recurring content is accurately captured during document processing.

Advanced Tips and Best Practices for Reading Word Documents in C#

To get the most out of programmatically reading Word documents, following these tips can help improve efficiency, reliability, and code maintainability:

• Use using Statements: Always wrap Document objects in using to ensure proper memory management.
• Check for Null or Empty Sections: Prevent errors by verifying sections, paragraphs, tables, or images exist before accessing them.
• Batch Reading Multiple Documents: Loop through a folder of Word files and apply the same extraction logic to each file. This helps automate workflows and consolidate extracted content efficiently.

Conclusion
