Implementation Guide

Feature 1: Converting Password-Protected Document to HTML

This feature focuses on converting a password-protected Word document into an HTML file while offering advanced options.

Step 1: Load the Protected Document

First, we need to load our protected document. Here’s how:

import com.groupdocs.conversion.options.load.WordProcessingLoadOptions;

String sourceDocument = "YOUR_DOCUMENT_DIRECTORY/SAMPLE_DOCX_WITH_PASSWORD.docx";
WordProcessingLoadOptions loadOptions = new WordProcessingLoadOptions();
loadOptions.setPassword("12345"); // Set the password to access your document

Step 2: Initialize Converter

Next, initialize the Converter object with our loaded options.

import com.groupdocs.conversion.Converter;
import com.groupdocs.conversion.options.convert.MarkupConvertOptions;

// Create a new converter instance
Converter converter = new Converter(sourceDocument, () -> loadOptions);

Step 3: Configure Conversion Options

Now, configure the conversion settings to ensure the desired output.

MarkupConvertOptions options = new MarkupConvertOptions();
options.setPageNumber(2); // Start from page 2
options.setFixedLayout(true); // Preserve the document's layout
options.setPagesCount(1); // Convert only one page

Step 4: Perform Conversion

Finally, convert your document using the specified options.

String convertedFile = "YOUR_OUTPUT_DIRECTORY/ConvertedToHtmlWithAdvancedOptions.html";
converter.convert(convertedFile, options);

Feature 2: Setting Conversion Options for Specific Pages

This feature demonstrates setting conversion parameters to focus on specific pages and layouts.

Step-by-Step Configuration

  1. Set Starting Page Number: Define where the conversion should begin.

convertOptions.setPageNumber(2); // Convert starting from page 2

2. **Enable Fixed Layout**: Ensure that your document's appearance remains consistent in HTML.
   ```java
convertOptions.setFixedLayout(true);
  1. Limit Pages Count: Specify how many pages to convert.

convertOptions.setPagesCount(1); // Convert only one page


### Troubleshooting Tips

3. **Integration with CMS**: Integrate conversions into content management systems for dynamic document display.

## Performance Considerations
### Optimization Tips
- Use appropriate memory settings to handle large documents efficiently.
- Optimize your Java environment for better resource utilization during conversion processes.

### Best Practices
