How to use CSV to JSON

Paste CSV data.
Convert it to formatted JSON.
Preview the result, then copy or use it.

A good use for this

Turning spreadsheet data into JSON for code, an API test, or a config file.

Limits

The first row is treated as headers, so a CSV without headers will lose its first data row into field names — check the preview before using the output.
