Free Excel to CSV

A free, unlimited Excel-to-CSV converter that runs entirely in your browser. No account, no paywall, no watermark on the CSV output.

Ideal for batch workflows that would otherwise need Excel or pandas.

1. Load the Excel file — no sign-up

Drop an .xlsx or .xls. Zero gates: no account, no email, no usage limit below 10 MB.

2. Pick the sheet to convert

Multi-sheet workbooks show every sheet in the dropdown. Swap sheets freely before export.

3. Download unlimited CSVs

UTF-8 output, no watermark, no rate limit. Use commercially, academically, or personally.

Is the free Excel to CSV tool actually unlimited?

Yes — no per-day or per-file cap below 10 MB. The only restriction is the 10 MB file size and 5,000-row preview limit.

Is my workbook uploaded on the free tier?

No. The workbook is decoded and converted in the browser, same as any paid tier would be.

Can I convert .xls legacy files for free?

Yes — both .xlsx and .xls are supported equally on the free tool.

Are there feature limits on the free Excel to CSV tool?

No hidden features. UTF-8 output, multi-sheet picker, custom separator, empty-row drop — all available.
