Frequently asked questions

Can I choose which sheet to export?

Yes, you can select any sheet from multi-sheet workbooks.

Can I copy the CSV instead of downloading it?

Yes. The Copy CSV button places the current sheet on your clipboard, and Download .csv saves it as a file.

What is the downloaded file named?

The export is named after the source workbook plus the sheet it came from, so multi-sheet exports stay distinguishable.

Are formulas exported as formulas?

No. CSV is a plain-text format, so the sheet is exported as the values it displays rather than as live formulas.

Is my workbook uploaded anywhere?

No. Parsing runs in your browser with SheetJS, and the workbook and CSV never leave your device.
