Data Privacy & Security

Your data security is our top priority. The entire conversion process happens locally in your web browser - your HTML content is never uploaded to any server. This means:

• No risk of data breaches or unauthorized access
• Complete confidentiality for sensitive business data
• No storage of your content on external servers
• Immediate deletion from browser memory after conversion

Best Practices

• Use the "Convert Numeric Values" option for financial or statistical data
• Enable "Trim Whitespace" to ensure clean, consistent data
• Use "data-sheet-name" attributes in your HTML to control Excel sheet names
• For large HTML files, extract only the relevant table sections
• Use browser developer tools to copy clean HTML table structures
• Preview complex tables before conversion to ensure proper structure
• Use the content analysis feature to understand your data volume

Performance Considerations

The converter is optimized for performance but here are some tips for best results:

• HTML files under 1MB convert almost instantly
• Files between 1-10MB may take a few seconds depending on complexity
• Documents with many complex tables may take longer to process
• Using simpler table structures improves processing speed
• Disabling certain options like basic styling can speed up conversion
