Frequently asked questions
What JSON structure works best?

The converter expects an array of objects where each object has the same keys - this maps naturally to CSV rows with consistent columns.


What happens with nested objects?

Nested objects are serialized as JSON strings within the CSV cell. Flatten your JSON first if you need nested fields as separate columns.


Can I convert CSV back to JSON?

The tool works in both directions. Switch to CSV input to convert back to a JSON array.


Is my data sent to a server?

Conversion runs entirely in your browser. No data is uploaded or stored.


Can I download the result?

Use the Download button to save the converted file directly to your device.
