About this tool

Convert tab-separated data to CSV and back, quoting fields safely, entirely in your browser.

Frequently asked questions

How are tricky fields handled?
Fields containing the target delimiter, a quote, or a newline are wrapped in double quotes with inner quotes doubled.
Does it keep existing quotes?
Yes. The parser understands quoted input fields, so values with commas or tabs survive the round trip.
