FAQ

JSON to CSV questions

See how privacy works

Is JSON to CSV free to use?

Yes. This tool is free to use in your browser and does not require an account.

Is processing local?

JSON to CSV uses Papa Parse and native JSON in the browser. Selected input is processed on your device when the required browser features are available. Application, library, model, security, and limited analytics requests may use the network.

What limits should I know about?

1 file · 50 MB max. Browser memory and format support also limit the files this tool can process.

What JSON shape works best for CSV conversion?

An array of objects with consistent keys works best because each object becomes a row and each key becomes a column.

Can I paste JSON instead of uploading a file?

Yes. The tool accepts pasted JSON text as well as a JSON file.
