FAQ
What JSON shape works best?
An array of flat objects. Nested objects are stringified into cells so the CSV stays rectangular.
Is my data uploaded?
No. Conversion runs entirely in JavaScript in your browser.
Can I convert CSV back to JSON?
Yes — switch direction and paste CSV with a header row.
How are commas and quotes handled?
Fields are RFC-style quoted when they contain commas, quotes, or newlines.
