About JSON Formatting

JSON (JavaScript Object Notation) is a lightweight data-interchange format that is easy to read and write for humans and machines.

Format pretty-prints JSON with 2-space indentation for readability. Minify removes all whitespace to reduce size. Validate checks if the input is valid JSON syntax.

The output includes syntax highlighting: keys, strings, numbers, booleans, and null.
