Frequently Asked Questions

Can this tool handle nested JSON objects?

Yes. The JSON to CSV converter can automatically flatten nested object properties using dot-notation headers (e.g. user.address.city).

Can I choose different delimiters like Tabs or Semicolons?

Yes. You can output standard comma-delimited CSV, tab-separated TSV, semicolon-delimited files for European Excel locales, or custom pipe characters.

Is my JSON payload sent to a third-party server?

No. The conversion logic runs entirely on your device using client-side JavaScript. No file or text payload is ever transmitted over the network.
