FAQ

Is my spreadsheet data uploaded?

Everything runs locally in your browser with JavaScript — nothing is uploaded, logged or stored. That matters when the CSV contains customer records.

Are quoted fields with commas supported?

Yes. Fields wrapped in double quotes may contain commas, newlines and escaped quotes.
