How are headers detected?

The first row of your CSV is automatically used as the header row. Each subsequent row becomes a JSON object with keys from the header.

Does this handle quoted fields?

Yes — fields wrapped in double quotes are handled correctly, including fields that contain commas or newlines.

Is this CSV to JSON converter private? Does it send my data to a server?

No. All conversion runs on your computer with JavaScript — your CSV stays on your device, and the tool works offline.
