Convert CSV to JSON or JSON to CSV in your browser. Paste spreadsheet data, map headers, download clean files — free, private, no signup.

Runs entirely in your browser — data is never uploaded.

How to use

Three steps. Zero friction.

01

Paste or upload CSV

Drop spreadsheet exports from Sheets, Excel, or Airtable. Processing stays in your browser.
