FAQs

What JSON formats work best in this converter?

Arrays of flat objects work best. Nested fields can be flattened before conversion for cleaner CSV output.

Does the JSON to CSV conversion happen on the server?

No. The conversion runs in your browser, so your input data is not uploaded to a backend service.

How can I avoid broken CSV columns?

Ensure keys are consistent across objects and values containing commas or newlines are quoted properly in output.
