JSON Formatter

Format, validate and minify JSON

What is a JSON Formatter?

A JSON formatter takes raw, unformatted JSON and outputs it in a human-readable, indented structure. It also validates your JSON and highlights syntax errors.

How to use

Paste your JSON into the input box. The formatter automatically detects and formats valid JSON in real time. Toggle between Format (pretty-print) and Minify (compact) modes.
