Frequently Asked Questions

Does CSV or JSON data leave the browser?

No. Parsing and conversion run locally in your browser.

Are quoted CSV fields supported?

Yes. The converter handles quoted commas, quoted newlines, and escaped double quotes.

What JSON shape does CSV input produce?

With headers enabled, CSV rows become objects keyed by the first row. Without headers, rows become arrays.
