Make Minified JSON Readable Again
Minified JSON is great for network transfer but terrible for reading. A single line of tightly packed keys, values, brackets, and braces gives you no visual cues about the data structure. Debugging minified JSON by eye is nearly impossible.
Our beautifier takes any valid JSON and formats it with proper indentation, line breaks, and consistent spacing. Nested objects and arrays are indented to show hierarchy. You can immediately see the structure, find the key you need, and understand the data at a glance.
It also works in reverse. If you need minified JSON for a compact payload, switch to minify mode and remove all whitespace. Two tools in one, both running entirely in your browser with no data transmitted to any server.
