JSON to CSV
JSON to CSV flattens an array of JSON objects into rows and columns a spreadsheet can open. Pass API responses, exported records or configuration data through it and you get a properly headed CSV with consistent columns — the fastest route from structured data to something you can filter, sort and share. It runs entirely in your browser.
How to use JSON to CSV
- Paste a JSON array of objects, or load a .json file.
- Press Convert and the keys from the first objects become column headers.
- Check the rows look right — missing keys are left blank rather than shifting columns.
- Download the CSV or copy it straight to the clipboard.
JSON to CSV FAQ
Does it handle nested objects?
Flattening is best for flat records. Deeply nested structures are stringified into a single cell so no data is dropped.
What if my JSON is a single object?
Wrap it in square brackets to make it an array of one record, and it converts normally.
Where does my data go?
Nowhere. Conversion happens in your browser, so sensitive records never leave your machine.
