CSV to JSON Converter

Paste CSV (first row = headers) and get a JSON array of objects. Quoted cells, commas inside quotes and escaped quotes are handled properly. Runs in your browser.

Notes on CSV input

The first row must be the column names — they become the JSON keys. All values come out as strings, because CSV itself has no number/boolean types; most JSON consumers are fine with that, or you can post-process. Both Windows (CRLF) and Unix line endings are accepted.

Frequently Asked Questions

My CSV has commas inside cells — will it break?

No, as long as those cells are quoted, as standard CSV writers do. The parser is quote-aware.

Can I convert the JSON back to CSV?

Yes — the JSON to CSV converter on this site does the reverse.
