JSON Formatter

What is JSON Formatter?

This JSON Formatter tool lets you format, beautify, validate, escape, unescape, and minify JSON directly in your browser. Your JSON never leaves your device. Raw JSON is frequently compressed into a single unreadable line or contains errors such as missing commas or mismatched brackets. This tool cleans and restructures your JSON into a readable and organized format, with syntax highlighting, indentation, and real-time error detection. It supports large JSON documents, API payloads, configuration files, data logs, nested JSON structures, and advanced validation.
