  2. Configure preferences like header row inclusion or output format (object list vs. array of arrays).
  3. Click "Convert" to render JSON output.
  4. Copy or download the file.

Frequently Asked Questions

How does CSV to JSON mapping work?

By default, the first row of your CSV is interpreted as headers (keys), and each subsequent row becomes an object with those keys.

Is there a file size limit?

Since conversion runs in your browser, the limit is based on your computer's RAM, but it easily supports files up to 10MB.

Can I choose standard arrays instead of objects?

Yes, you can toggle the formatting to export an array of arrays if you do not want to use column headers as keys.
