Frequently asked questions (Excel to HTML)

Does this tool support large Excel files?

Yes – it works within your browser's memory limits. Most standard Excel files (up to 50MB) convert instantly. Very large files depend on your device’s available RAM.

Can I edit the Excel data before converting to HTML?

Absolutely. The preview table is fully editable. You can change cell values, insert or delete rows, and even rename headers – then generate HTML from the modified data. All live in your browser.

Is the generated HTML table responsive?

The HTML output uses a clean <table> structure with <thead> and <tbody>. You can easily add CSS to make it responsive (e.g., overflow-x: auto) or style it further.

Does it preserve Excel formatting (colors, fonts, merged cells)?

CSV‑to‑HTML conversion focuses on raw data, not visual formatting. The tool generates a semantic HTML table with your data intact. For advanced styling (colors, borders, etc.), you can add custom CSS after export.

Is my Excel file uploaded to a server?

No. The tool runs entirely in your browser using the SheetJS library. Your file never leaves your computer – that’s why it works offline too.

Is this Excel to HTML converter really free?

Yes, completely free. No hidden fees, no premium tiers, no watermarks. DataFrog believes essential tools should be accessible to everyone.
