JSON to CSV Converter — Free, Local | How to use and interpret results
Turn JSON records into CSV text and a file named rows.csv. This is a tabular export step, not a nested-data transformation language.
- Runs in your browser
- Nothing is uploaded
- No signup; device limits apply
Numbers stay on your device. Nothing is sent to a server.
How to use this tool
Paste one valid JSON object or an array of objects. Convert newline-delimited JSON into an array first; separate top-level objects are not one JSON document.
Results and examples
For [{"name":"Ada","score":92}], name and score become headers and Ada and 92 occupy one data row. Inspect column order and quoting before importing the output into a spreadsheet.

Limitations
- Nested objects are not flattened and can appear as [object Object].
- Large payloads consume browser memory; try a representative subset before a full export.
