Beautify, minify, and validate your JSON data in real-time.
JSON (JavaScript Object Notation) is the backbone of modern web communication. While machines love its compact nature, humans often find it impossible to read when minified or poorly structured.
Our tool checks for common errors like trailing commas, single quotes instead of double quotes, and unquoted keys.
Everything happens in your browser. Your data never touches our server, keeping your API keys and sensitive payloads 100% private.
"key": "value"
Always use double quotes for keys and string values.
[]
Arrays use square brackets; objects use curly braces {}.
null, true, false
Booleans and null values should not be quoted.
No Commas
Never leave a trailing comma after the last item in a list.
