JSON to CSV
Flatten JSON arrays into spreadsheet rows.
How to use the JSON to CSV
Provide the source data
Paste text or select files, depending on the converter. Detection reports the format that was recognised.
Choose the target format
Set delimiters, headers or archive options so the output matches the system that will consume it.
Validate and download
Check the preview or entry list, then copy or download the converted result.
What JSON to CSV is for
Turn an array of objects into CSV with a union of columns, proper quoting and downloadable output. Nested values are serialised into cells.
The JSON to CSV is part of the Converters collection on ToolFlow. It is designed for one concrete job: flatten JSON arrays into spreadsheet rows. Everything runs client-side, so you can use it with sensitive material without creating a copy on someone else's server.
Common use cases

Good to know
- No account is required, and there is no usage limit on the browser tool.
- Processing happens locally. Files are read from disk and the result is written back to your downloads folder.
- Results are reproducible: the same input and options produce the same output, with no hidden server round-trip.
- If the tool needs a live data source, the page states it explicitly instead of silently failing.
