About this tool

Turn a CSV export into JSON — or a JSON array back into CSV — with a live table preview so you can see the data is parsed the way you expect. Headers become keys, quoted fields and embedded commas are handled correctly, and the output is ready to paste into code, a spreadsheet or an API call.

The converter runs entirely in your browser, which makes it safe for customer lists, exports with email addresses and any other data you should not upload to a random website.

How to use it

  1. Paste CSV or JSON into the input (or drop a file).
  2. Click CSV → JSON or JSON → CSV and check the table preview.
  3. Copy the output.

Frequently asked questions

Does it handle commas inside quoted fields?

Yes. Quoted fields, escaped quotes and line breaks inside quotes follow the RFC 4180 CSV conventions.

What JSON shape does it produce?

An array of objects, one object per row, with the header row as keys — the format most APIs and JavaScript code expect.

Is my data uploaded?

No. Parsing and conversion happen in your browser.
