Beautify and format your JSON data with custom indentation options. Make your JSON readable and pretty!
No JSON to display
Enter JSON in the editor to see formatted output
JSON formatting (also called beautifying or pretty-printing) adds proper indentation, line breaks, and spacing to JSON data, making it human-readable and easier to understand.
When JSON is minified or compressed, it's difficult to read. A JSON formatter restores readability by adding proper structure, making it ideal for debugging, documentation, and code review.
Properly indented JSON is much easier to read and understand, especially for complex nested structures
Spot errors, missing commas, or structural issues quickly when JSON is properly formatted
Share formatted JSON in documentation, code reviews, or team discussions for clarity
Work faster with readable JSON - understand API responses and config files at a glance
The best JSON formatter is one that runs client-side for privacy, offers customizable indentation, validates syntax, and is completely free. Our JSON formatter provides all these features with 2-space, 4-space, or tab indentation options.
Simply paste your JSON into our formatter, choose your preferred indentation (2 spaces, 4 spaces, or tabs), and click Format. The tool will automatically add proper line breaks and spacing throughout your JSON structure.
Yes! In VS Code, you can format JSON by pressing Shift+Alt+F (Windows/Linux) orShift+Option+F (Mac). However, our online formatter offers more control with custom indentation options and works in any browser without setup.
Absolutely! All formatting happens 100% in your browser using JavaScript. Your JSON data never leaves your device and is never uploaded to any server, ensuring complete privacy and security.
Formatting (or beautifying) adds indentation and line breaks to make JSON human-readable. Minifying does the opposite - it removes all whitespace to reduce file size. Use formatting for development and minifying for production. Try our JSON Minifier for compression.
Our formatter will attempt to format your JSON, but if it contains syntax errors, you'll need to fix them first. Use our JSON Validator to identify and fix errors, then format the corrected JSON.
This is largely a matter of preference and team standards. Most JavaScript projects use 2 spaces, while many other languages prefer 4 spaces. Tabs offer flexibility but can display differently across editors. Choose what matches your project's style guide.
Yes! Our formatter handles any valid JSON structure, including deeply nested objects, arrays, mixed data types, and complex hierarchies. Each level will be properly indented for maximum readability.
