About JSON and CSV

JSON (JavaScript Object Notation, .json) and CSV (Comma-Separated Values, .csv) are common structured data formats. This converter transforms JSON into CSV entirely in your browser — no data is uploaded to any server.

Frequently asked questions

Is this JSON to CSV converter free?

Yes, completely free. All conversion happens in your browser, so your data never leaves your device.

Do I need to upload my .json file?

No. Paste the content directly. There is no server-side processing, no file upload, and no storage.

Is there a limit on data size?

It depends on your browser, but most machines handle tens of thousands of rows without issue. For very large files, performance may vary.
