Common questions

JSON to CSV,
explained.

What JSON structure works best?+

Use an array of objects where each object represents one row. A single object is also accepted and becomes one row.

Can the converter handle missing fields?+

Yes. Missing values become empty CSV cells while the column order remains consistent.

Are my files uploaded?+

No. TidyFormat processes the conversion locally in your browser. Your input and output files are not sent to our servers.
