Frequently Asked Questions

What if my CSV has quoted values?

Our parser automatically handles quoted values and commas within quotes correctly.

Can I convert CSV without headers?

Yes! Uncheck "first row as headers" and we'll generate generic column names (column1, column2, etc.).

Is my data sent to a server?

No! All conversion happens locally in your browser. Your data never leaves your device.
