How to use Excel to CSV
- Select an Excel workbook.
- Click “Convert to CSV”.

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.
