FAQ

Will nested JSON become multiple CSV tables?

No. This tool keeps the workflow simple and flattens nested keys into columns where possible.

Can I convert a single JSON object instead of an array?

Yes. A single object is treated like one CSV row.

What happens to arrays inside objects?

Simple arrays may be joined into one field, while more complex arrays can be preserved as JSON text in the CSV cell.

Does the converter upload business data?

No. It runs locally in your browser, so your JSON is not uploaded.
