JSON to CSV

How to use JSON to CSV

1. Paste your text or choose a supported file. Supported inputs: JSON.
2. Review the settings, then start. Your content is processed in your browser and never uploaded.
3. Check the output and download it. Download before closing the tab; local results are not saved.

Useful to know

Convert a JSON array of records to CSV using the union of their column names. Nested values can be serialized as JSON or rejected explicitly. Large numeric tokens retain their precision.

Literal export preserves cells. Enable spreadsheet-safe export to prefix potential formulas before opening untrusted data in a spreadsheet.

Supported formats and limits

Up to 5 MB per file. One input per job. Outputs use CSV format. Busy queues may ask you to try again shortly.

Do I need an account?

No. Every tool works for guests. Your favorites and saved settings stay on this device and do not include file contents.
