How to use JSON Formatter
- 1
Paste or type raw JSON into the input panel — minified, malformed spacing, or already-formatted JSON all work.
- 2
The output panel updates automatically with indented, syntax-highlighted JSON.
- 3
Adjust indentation width if the tool exposes that option, then copy the formatted result or download it as a .json file.
Common use cases
- •Making a minified API response readable while debugging
- •Cleaning up JSON before pasting it into documentation or a bug report
- •Quickly eyeballing the structure of a config file or webhook payload
