How to convert Excel to CSV

  3. Click "Convert" to download a .csv file, or a .zip of .csv files if the workbook has multiple sheets.

FAQ

Is my file uploaded to a server?

No — everything runs locally in your browser; your file never leaves your device.

What happens if my workbook has multiple sheets?

Each sheet becomes its own .csv file, packaged together in a single .zip download. A workbook with only one sheet downloads as a plain .csv file instead.
