How this tool works

Paste JSON text and ToolRefinery parses and re-serializes it with the indentation you choose, entirely in your browser.

Paste text directly into the tool. Maximum input length: 1953 KB.

For this version, ToolRefinery processes the text you paste on your device. It is not sent to a ToolRefinery processing server.

Check JSON validity locally and see a clear parse error when it fails.

Convert a JSON array of objects into CSV in your browser.
