Frequently Asked Questions
How does the JSON→CSV converter work?
It parses your JSON array, extracts the header keys from the first object, then serializes each row with proper comma-quote escaping.
Can I convert nested JSON?
Nested objects are stringified (JSON.stringify) — use the outer object for simple flat-to-flat CSV conversion.
Is this converter free?
Yes — 100% free, client-side, no signups, no limits. Download as many CSV files as you need.
