Что такое водяной знак в Microsoft Word?
Водяной знак в Word — это полупрозрачный дизайн, текст или изображение, которое появляется за основным содержимым страницы документа. Он не мешает самому содержимому, но остается видимым для читателей.
Распространенные типы водяных знаков включают:
- Текстовые водяные знаки: «Конфиденциально», «Черновик», «Образец» и т. д.
- Графические водяные знаки: логотипы компаний или фоновые изображения
- Пользовательские водяные знаки: элементы брендинга или уникальные идентификаторы
Преимущества использования водяных знаков в документах Word
Водяные знаки служат нескольким важным целям:
- Защита конфиденциального содержимого путем четкой маркировки документов как конфиденциальных
- Указание статуса документа, такого как черновик, на рассмотрении или окончательный
- Брендирование документов с помощью логотипов или названий компаний
- Предотвращение несанкционированного распространения или неправомерного использования

Perform PDF OCR with Python (Extract Text from Scanned PDF)
In daily work, extracting text from PDF files is a common task. For standard digital documents—such as those exported from Word to PDF—this process is usually straightforward. However, things get tricky when dealing with scanned PDFs, which are essentially images of printed documents. In such cases, traditional text extraction methods fail, and OCR (Optical Character Recognition) becomes necessary to recognize and convert the text within images into editable content.
In this article, we’ll walk through how to perform PDF OCR using Python to automate this workflow and significantly reduce manual effort.
- Why OCR is Needed for PDF Text Extraction
- Best Python OCR Libraries for PDF Processing
- Convert PDF Pages to Images Using Python
- Scan and Extract Text from Images Using Spire.OCR
- Conclusion
Why OCR is Needed for PDF Text Extraction
When it comes to extracting text from PDF files, one important factor that determines your approach is the type of PDF. Generally, PDFs fall into two categories: scanned (image-based) PDFs and searchable PDFs. Each requires a different strategy for text extraction.
-
Scanned PDFs are typically created by digitizing physical documents such as books, invoices, contracts, or magazines. While the text appears readable to the human eye, it's actually embedded as an image—making it inaccessible to traditional text extraction tools. Older digital files or password-protected PDFs may also lack an actual text layer.
-
Searchable PDFs, on the other hand, contain a hidden text layer that allows computers to search, copy, or parse the content. These files are usually generated directly from applications like Microsoft Word or PDF editors and are much easier to process programmatically.
This distinction highlights the importance of OCR (Optical Character Recognition) when working with scanned PDFs. With tools like Python PDF OCR, we can convert these image-based PDFs into images, run OCR to recognize the text, and extract it for further use—all in an automated way.
Best Python OCR Libraries for PDF Processing
Before diving into the implementation, let’s take a quick look at the tools we’ll be using in this tutorial. To simplify the process, we’ll use Spire.PDF for Python and Spire.OCR for Python to perform PDF OCR in Python.
- Spire.PDF will handle the conversion from PDF to images.
- Spire.OCR, a powerful OCR tool for PDF files, will recognize the text in those images and extract it as editable content.
You can install Spire.PDF using the following pip command:
pip install spire.pdf
and install Spire.OCR with:
pip install spire.ocr
Alternatively, you can download and install them manually by visiting the official Spire.PDF and Spire.OCR pages.
Convert PDF Pages to Images Using Python
Before we dive into Python PDF OCR, it's crucial to understand a foundational step: OCR technology doesn't directly process PDF files. Especially with image-based PDFs (like those created from scanned documents), we first need to convert them into individual image files.
Converting PDFs to images using the Spire.PDF library is straightforward. You simply load your target PDF document and then iterate through each page. For every page, call the PdfDocument.SaveAsImage() method to save it as a separate image file. Once this step is complete, your images are ready for the subsequent OCR process.
Here's a code example showing how to convert PDF to PNG:
from spire.pdf import *
# Load the PDF file
pdf = PdfDocument()
pdf.LoadFromFile("/AI-Generated Art.pdf")
# Loop through pages and save as images
for i in range(pdf.Pages.Count):
# Convert each page to image
with pdf.SaveAsImage(i) as image:
# Save in different formats as needed
image.Save(f"/output/pdftoimage/ToImage_{i}.png")
# image.Save(f"Output/ToImage_{i}.jpg")
# image.Save(f"Output/ToImage_{i}.bmp")
# Close the PDF document
pdf.Close()
Conversion result preview: 
Scan and Extract Text from Images Using Spire.OCR
After converting the scanned PDF into images, we can now move on to OCR PDF with Python and to extract text from the PDF. With OcrScanner.Scan() from Spire.OCR, recognizing text in images becomes straightforward. It supports multiple languages such as English, Chinese, French, and German. Once the text is extracted, you can easily save it to a .txt file or generate a Word document.
The code example below shows how to OCR the first PDF page and export to text in Python:
from spire.ocr import *
# Create OCR scanner instance
scanner = OcrScanner()
# Configure OCR model path and language
configureOptions = ConfigureOptions()
configureOptions.ModelPath = r'E:/DownloadsNew/win-x64/'
configureOptions.Language = 'English'
scanner.ConfigureDependencies(configureOptions)
# Perform OCR on the image
scanner.Scan(r'/output/pdftoimage/ToImage_0.png')
# Save extracted text to file
text = scanner.Text.ToString()
with open('/output/scannedpdfoutput.txt', 'a', encoding='utf-8') as file:
file.write(text + '\n')
Result preview: 
The Conclusion
In this article, we covered how to perform PDF OCR with Python—from converting PDFs to images, to recognizing text with OCR, and finally saving the extracted content as a plain text file. With this streamlined approach, extracting text from scanned PDFs becomes effortless.

What is a Watermark in Microsoft Word?
A watermark in Word is a semi-transparent design, text, or image that appears behind the main content of a document page. It does not interfere with the content itself, but remains visible to readers.
Common watermark types include:
- Text Watermarks: "Confidential", "Draft", "Sample", etc.
- Image Watermarks: Company logos or background images
- Custom Watermarks: Branding elements or unique identifiers
Benefits of Using Watermarks in Word Documents
Watermarks serve several important purposes:
- Protect sensitive content by clearly marking documents as confidential
- Indicate document status, such as draft, review, or final
- Brand documents with logos or company names
- Discourage unauthorized distribution or misuse
Part 1: How to Add Watermarks in Word Manually (Step-by-Step Guide)
Microsoft Word makes it easy to add watermarks, whether you're using a built-in option or creating your own. You can choose from a set of predefined watermarks like “Confidential” or “Draft,” or create custom text and image watermarks to align with your document's purpose and branding.

Why Convert Markdown to PDF and Excel?
Markdown is great for writing, but it has limitations when sharing or processing documents:
- PDF files provide a fixed-layout, platform-independent format ideal for sharing polished reports, manuals, or official documentation. PDFs maintain the original style and layout regardless of device or software.
- Excel files are essential when Markdown contains tabular data that you want to analyze, manipulate, or integrate into business processes. Converting Markdown tables to Excel spreadsheets lets you utilize formulas, filters, charts, and data tools effectively.
By converting Markdown to these formats programmatically in C#, you can automate documentation workflows, batch-process files, and integrate with other .NET applications.
Prerequisites (Library & Environment Setup)
Before you start converting Markdown files, ensure your development environment meets the following requirements:
- .NET Framework or .NET Core installed.
- Spire.XLS for .NET: A comprehensive Excel library that supports loading Markdown and exporting to PDF and Excel formats.
Install Spire.XLS via NuGet
You can easily install Spire.XLS in your C# project via NuGet by opening the NuGet Package Manager and executing the following command:
Install-Package Spire.XLS
This package provides all the necessary classes and methods to load Markdown and export documents without relying on Microsoft Office automation.
How to Convert Markdown to PDF in C# (Step-by-Step with Code)
To convert a Markdown file to PDF in C#, follow the steps below:
Step 1: Load the Markdown File
Create a new instance of the Workbook class and load your Markdown file:
Workbook workbook = new Workbook();
workbook.LoadFromMarkdown("test.md");
This method parses the Markdown content, including text and tables, into an Excel workbook structure that Spire.XLS can manipulate.
Step 2: Customize Conversion Settings (Optional)
After loading the Markdown file, you can apply conversion settings to ensure the PDF output retains a clean and readable layout. For example, enabling the SheetFitToPage option ensures that the entire Markdown content fits within a single PDF page.
workbook.ConverterSetting.SheetFitToPage = true;
Step 3: Export as PDF
Save the workbook as a PDF file:
workbook.SaveToFile("output.pdf", FileFormat.PDF);
This generates a well-formatted PDF document preserving the Markdown layout and styling suitable for printing or sharing.

How to Convert Markdown to Excel in C# (Step-by-Step with Code)
After loading the Markdown file into the workbook, you can also export it to an Excel spreadsheet format:
workbook.SaveToFile("output.xls", ExcelVersion.Version97to2003);
You may also choose other Excel versions depending on your target compatibility:
workbook.SaveToFile("output.xlsx", ExcelVersion.Version2016);
The exported Excel file retains tables and structured data from your Markdown, allowing further analysis or manipulation.

Complete C# Code Example: Convert Markdown to PDF and Excel in One Go
Here’s the full example combining both PDF and Excel exports in a single run:
using Spire.Xls;
namespace MarkdownToPdfAndExcel
{
internal class Program
{
static void Main(string[] args)
{
// Initialize the workbook
Workbook workbook = new Workbook();
// Load Markdown content
workbook.LoadFromMarkdown("test.md");
// Fit the sheet data to one page (optional)
workbook.ConverterSetting.SheetFitToPage = true;
// Export to PDF
workbook.SaveToFile("output.pdf", FileFormat.PDF);
// Export to xls (Excel 97-2003 format)
workbook.SaveToFile("output.xls", ExcelVersion.Version97to2003);
// Export to xlsx (Excel 2016 format)
workbook.SaveToFile("output.xlsx", ExcelVersion.Version2016);
workbook.Dispose();
}
}
}
Best Practices for Markdown Conversion
- Use UTF-8 Encoding: Ensure your Markdown files use UTF-8 encoding, especially if they contain special or non-English characters. This ensures proper character display and avoids encoding errors during conversion.
- Maintain Clean and Well-Formatted Markdown Tables: To achieve accurate and reliable Excel conversions, structure your Markdown tables carefully. Use consistent pipe (|) delimiters and avoid malformed syntax to preserve table integrity in the output spreadsheet.
- Load Once, Export Multiple Formats: For optimal performance, load your Markdown content into the Workbook object a single time, then export it to various formats such as PDF and Excel. This reduces processing overhead and speeds up batch conversions.
- Assess Markdown Complexity: Spire.XLS effectively supports basic Markdown syntax, such as headings and tables. However, advanced features like embedded images or code blocks with syntax highlighting might require pre-processing or conversion through intermediate formats like HTML.
- Choose Appropriate Excel Export Versions: To maximize compatibility with your users’ software, select the Excel file format based on their environment. For example, use the .xls format for legacy Excel 97–2003 users, and .xlsx for Excel 2007 and later versions to ensure broad accessibility and full feature support.

Add JAR Manually
Download Spire.XLS for Java and add the JAR to your classpath manually. For smaller projects, you can also use the Free Spire.XLS for Java.
Convert a CSV File to Excel Using Java
The simplest use case is to convert a single .csv file into .xlsx or .xls format in Java. Spire.XLS makes this process easy using just two methods: loadFromFile() to read the CSV, and saveToFile() to export it as Excel.
import com.spire.xls.*;
public class CsvToXlsx {
public static void main(String[] args) {
Workbook workbook = new Workbook();
workbook.loadFromFile("data.csv", ",");
workbook.saveToFile("output.xlsx", ExcelVersion.Version2013);
}
}
To generate .xls format instead, use ExcelVersion.Version97to2003.
Below is the output Excel file generated after converting the CSV:

You can also specify a custom delimiter or choose the row/column to begin inserting data — useful if your sheet has titles or a fixed layout.
workbook.loadFromFile("data_semicolon.csv", ";", 3, 2);
Format Excel Output Using Java
When you're exporting CSV for reporting or customer-facing documents, it's often necessary to apply styles for better readability and presentation. Spire.XLS allows you to set cell fonts, colors, and number formats using the CellStyle class, automatically adjust column widths to fit content, and more.
Example: Apply Styling and Auto-Fit Columns
import com.spire.xls.*;
public class CsvToXlsx {
public static void main(String[] args) {
Workbook workbook = new Workbook();
workbook.loadFromFile("data.csv", ",");
Worksheet sheet = workbook.getWorksheets().get(0);
// Format header row
CellStyle headerStyle = workbook.getStyles().addStyle("Header");
headerStyle.getFont().isBold(true);
headerStyle.setKnownColor(ExcelColors.LightYellow);
for (int col = 1; col <= sheet.getLastColumn(); col++) {
sheet.getCellRange(1, col).setStyle(headerStyle);
}
// Format numeric column
CellStyle numStyle = workbook.getStyles().addStyle("Numbers");
numStyle.setNumberFormat("#,##0.00");
sheet.getCellRange("B2:B100").setStyle(numStyle);
// Auto-fit all columns
for (int i = 1; i <= sheet.getLastRow(); i++) {
sheet.autoFitColumn(i);
}
workbook.saveToFile("formatted_output.xlsx", ExcelVersion.Version2013);
}
}
Here’s what the styled Excel output looks like with formatted headers and numeric columns:

Need to use a pre-designed Excel template? You can load an existing .xlsx file and insert your data using methods like insertArray(). Just note that formatting won’t automatically apply — use CellStyle to style your data programmatically.
Merge Multiple CSV Files into One Excel File
When handling batch processing or multi-source datasets, it’s common to combine multiple CSV files into a single Excel workbook. Spire.XLS lets you:
- Merge each CSV into a separate worksheet, or
- Append all CSV content into a single worksheet
Option 1: Separate Worksheets per CSV
import com.spire.xls.*;
import java.io.File;
public class CsvToXlsx {
public static void main(String[] args) {
// Get the CSV file names
File[] csvFiles = new File("CSVs/").listFiles((dir, name) -> name.endsWith(".csv"));
// Create a workbook and clear all worksheets
Workbook workbook = new Workbook();
workbook.getWorksheets().clear();
for (File csv : csvFiles) {
// Load the CSV file
Workbook temp = new Workbook();
temp.loadFromFile(csv.getAbsolutePath(), ",");
// Append the CSV file to the workbook as a worksheet
workbook.getWorksheets().addCopy(temp.getWorksheets().get(0));
}
// Save the workbook
workbook.saveToFile("merged.xlsx", ExcelVersion.Version2016);
}
}
Each CSV file is placed into its own worksheet in the final Excel file:

Option 2: All Data in a Single Worksheet
import com.spire.xls.*;
import java.io.File;
public class CsvToXlsx {
public static void main(String[] args) {
// Get the CSV file names
File[] csvFiles = new File("CSVs/").listFiles((dir, name) -> name.endsWith(".csv"));
// Create a workbook
Workbook workbook = new Workbook();
// Clear default sheets and add a new one
workbook.getWorksheets().clear();
Worksheet sheet = workbook.getWorksheets().add("Sample");
int startRow = 1;
boolean isFirstFile = true;
for (File csv : csvFiles) {
// Load the CSV data
Workbook temp = new Workbook();
temp.loadFromFile(csv.getAbsolutePath(), ",");
Worksheet tempSheet = temp.getWorksheets().get(0);
// Check if it's the first file
int startReadRow = isFirstFile ? 1 : 2;
isFirstFile = false;
// Copy the CSV data to the sheet
for (int r = startReadRow; r <= tempSheet.getLastRow(); r++) {
for (int c = 1; c <= tempSheet.getLastColumn(); c++) {
sheet.getCellRange(startRow, c).setValue(tempSheet.getCellRange(r, c).getText());
}
startRow++;
}
}
// Save the merged workbook
workbook.saveToFile("merged_single_sheet.xlsx", ExcelVersion.Version2016);
}
}
Below is the final Excel sheet with all CSV data merged into a single worksheet:
