JSON Formatter & Validator

How to use the JSON Formatter

1. Paste your raw or minified JSON into the input box on the left.
2. Click Format to beautify with 2-space indentation, or Minify to compress it to a single line.
3. Click Validate to check whether the JSON is syntactically correct without transforming it.
4. Click Copy to copy the output to your clipboard.

What is JSON formatting?

JSON (JavaScript Object Notation) is valid regardless of whitespace, but minified JSON is hard to read. Formatting — also called beautifying or pretty-printing — adds consistent indentation and line breaks so the structure becomes clear at a glance.

When should you minify JSON?

Minified JSON reduces file size, which speeds up API responses and reduces bandwidth usage. It is standard practice to minify JSON before sending it over a network, while keeping a formatted version in your source files.
