Frequently Asked Questions

What file formats are supported?

This converter supports .XLSX (Excel 2007 and newer) and .XLS (Excel 97-2003) formats. If your file uses .CSV format, please use our dedicated CSV to HTML table converter instead.

Can I use the HTML output on any website?

Yes. The generated HTML uses standard table tags with inline CSS styles, making it compatible with virtually all website builders, CMS platforms (WordPress, Joomla, etc.), and email clients.

How is privacy handled?

Everything runs locally: Excel to HTML Converter and other values are processed on your device, never sent to a server using the SheetJS library. Your Excel file is never uploaded to any server. This makes the tool safe for sensitive business data, financial reports, and personal information.

Does it support formulas and charts?

Formulas are evaluated and the resulting values are displayed in the HTML table. Charts are not converted — only the underlying data is shown. For chart data, the numbers in the chart's source range are included in the output.

What's the maximum file size?

Since all processing is done in-browser, the limit depends on your device's memory. Files up to 10MB typically work well. For very large Excel files with thousands of rows, consider splitting them before conversion.
