Frequently asked questions

Which sheet gets exported?

Each sheet in the workbook is exported as its own CSV file — multiple sheets come back bundled in a ZIP. Formulas are exported as their computed values.

Is Excel to CSV free to use?

Yes — Excel to CSV is completely free with no limits, no watermarks and no sign-up. It runs in your browser, so there is nothing to pay for.

Are my files uploaded or stored anywhere?

No. This tool does all its work locally in your browser using your own device's power. Your files never leave your device and we never see them.

Do I need to install anything or create an account?

No installation and no account needed. Excel to CSV works on any modern browser — Windows, Mac, Linux, Android and iPhone.

How do I use Excel to CSV?

Open the tool, add your file (or paste your content), adjust any options, then press “Convert to CSV”. Your result is ready to download in seconds.
