Why format your JSON?
JSON (JavaScript Object Notation) is the standard format for data exchange on the web. Proper formatting makes it readable, debuggable, and less prone to errors.
Prettifying JSON
Raw JSON from APIs is often minified (squashed onto a single line) to save bandwidth. Formatting it with proper indentation allows developers to quickly scan the hierarchy and locate bugs in the data structure.
Validation
A missing comma or an unescaped quote will completely break JSON parsing. Our tool instantly validates your JSON as you format it, giving you immediate feedback on syntax errors. And it all happens securely in your browser!
