Spreadsheet paste to CSV
When you copy cells from Excel, Google Sheets or Numbers you get tab-separated text. This tool turns that into standard CSV, quoting any field that contains a comma, quote or line break so the result is valid everywhere.
Frequently asked questions
Is my data uploaded anywhere?
No. The conversion runs entirely in your browser; nothing is sent to a server.
How are commas inside fields handled?
Any field containing a comma, quote or newline is wrapped in double quotes, per the CSV standard.
Where does TSV come from?
Copying cells from a spreadsheet puts tab-separated text on your clipboard — paste it straight in.
