Frequently Asked Questions

How do I convert CSV with headers to JSON objects?

Keep 'First row is header' enabled. The first line becomes object keys, and each next row maps to a JSON object.

Can this parse semicolon or tab-delimited files?

Yes. Switch the delimiter to semicolon, tab, pipe, or comma before converting.

Will this tool preserve quoted commas inside fields?

Yes. Quoted values like "New York, NY" stay as a single field during parsing.

Is my CSV uploaded to a server?

No. Conversion happens fully client-side in your browser.
