How to use the TSV to CSV Converter

  1. Enter or paste your input in the box (or set the options, if the tool needs no input).
  2. Adjust the options to match what you need — the result updates as you type.
  3. Copy the result or download it, and keep editing if you want a different outcome.

What does this tool do?

Values that contain commas, quotes or line breaks are quoted correctly so the CSV opens cleanly in Excel and imports without shifting columns. Quoted TSV fields are unwrapped first.

Everything runs in your browser, so nothing you enter is uploaded or stored.

Why use it?

  • Free, with no sign-up and no limits.
  • Instant results as you type.
  • Private — your data stays on your device.

Example

Input: a⇥b,c

Result: a,"b,c"
