How do I convert CSV to JSON?

Paste your CSV data in the input field, ensure 'First row is header' is checked if applicable, and the JSON output will be generated automatically. Each row becomes a JSON object.

Can I convert JSON back to CSV?

Yes! Switch to 'JSON to CSV' mode and paste your JSON array. The tool will generate a CSV with headers from the JSON object keys.

What delimiters are supported?

We support comma (,), semicolon (;), tab, and pipe (|) delimiters. Choose the one that matches your CSV format from the delimiter dropdown.

How are quoted fields handled?

Our parser properly handles quoted fields, including fields containing commas, newlines, and escaped quotes (double quotes within quoted fields).

Is there a row limit?

There's no hard limit, but for best performance we recommend files under 10,000 rows. The table preview shows the first 20 rows.
