What is JSON formatting?

JSON formatting (or beautifying) takes compact, minified JSON and adds proper indentation and line breaks to make it human-readable.

When do you need it?

How to use
  1. 1) Paste your JSON data into the input box.
  2. 2) Click the Format button to beautify.
  3. 3) Copy the result or download as a file.
