Choose an HTML file containing one or more tables. The converter finds each table, uses its caption or order for the sheet name, previews the first table, and creates a new Excel workbook.

What this tool does
HTML tables become workbook worksheets; merged cells and basic text are retained where the browser can identify them.
The output focuses on table data. Page styling, scripts, images, and interactive controls are not transferred.
HTML files with standard table markup are supported. Complex tables may be flattened to a rectangular worksheet.

FAQ
Does HTML Table to Excel Converter upload my spreadsheet?
No. Processing happens in your browser, and the selected file is not sent to Calloffice.
What happens to formulas when I use this html tool?
Formula cells are preserved where the selected operation can retain them, but the browser does not reproduce Excel's full calculation engine.
Can I use large files with HTML Table to Excel Converter?
Yes, within your browser's available memory. The preview is capped, and very large workbooks may take longer or need to be split first.
How are dates, IDs, and leading zeros handled?
The tool uses displayed spreadsheet values where appropriate and avoids intentional numeric conversion unless the selected operation requires it. Review identifier columns after export.
What should I check before using the downloaded file?
Check the preview, output counts, headers, and a few representative rows. Keep the original file until the result has been verified.
