About this tool
CSV in, JSON out. Or the other way. A simple swap that saves an hour of copy-paste.
Paste or upload a table and convert it between CSV and JSON so it drops into code, a spreadsheet, or an API without a fight.
Useful when a developer wants JSON but your data lives in a spreadsheet, or vice versa.
Runs in your browser — the data doesn't get uploaded.
Your data stays on your device. (We run anonymous analytics — see privacy policy.)
Tip: watch the first row; that's usually your column names and it decides the JSON keys. That's it.
