About the CSV to JSON Converter
Spreadsheets speak CSV; APIs speak JSON. This converter translates in both directions at once: paste CSV with a header row and get a pretty-printed JSON array of objects, or paste that JSON array and get clean CSV back. Delimiter detection handles commas, semicolons and tabs automatically, so exports from Excel, Google Sheets and European-locale spreadsheets all just work.
Quoted cells containing commas, double quotes or line breaks are parsed correctly, and everything runs locally in your browser — which makes the tool safe for customer exports and other data you should never upload to a server.
How to use it
- 1Paste CSV with a header row to see the JSON output.
- 2Or paste a JSON array of flat objects to see CSV.
- 3Copy the side you need — parse errors appear inline with the reason.
