- Export data for a system that only accepts CSV
- Get a plain, simple version of a sheet
- Prepare a file to import into another app

Is it private?
Yes. Excel to CSV runs 100% inside your web browser. Your files are never uploaded to a server, so even we can’t see them. That makes it a safe choice for sensitive spreadsheets, contracts, and personal documents.
Tips for the best result
- A multi-sheet workbook gives one CSV per sheet, delivered as a zip.
- CSV keeps only the data — colours and formulas are not saved.
