What is JSON to CSV?
Paste a JSON array of objects and get a ready-to-use CSV: columns are detected automatically across all records, values are quoted per RFC 4180, and you can pick comma, semicolon or tab as the delimiter. Perfect for moving API responses into Excel, Google Sheets or a database import.
How to use JSON to CSV
- Paste your JSON array into the input box or click “Load sample” to try it.
- Adjust the options in the toolbar if needed (delimiter, table name, format …).
- Click the convert button — the CSV appears instantly in the output pane.
- Copy the result with one click or download it as a file.

Yes — 100% free, no signup, no limits, no watermarks. Use it as often as you like.
How are nested objects handled?
Nested objects and arrays are serialized as JSON strings inside their cell, so no data is lost. For fully flat output, run the JSON through our JSON Flattener first.

No. The conversion runs entirely in your browser with JavaScript — your data never leaves your device, which makes the tool safe even for confidential files.
