Format, validate, minify and beautify your JSON data instantly
JSON (JavaScript Object Notation) is a lightweight data interchange format. It's easy for humans to read and write, and easy for machines to parse and generate.
Keys must be strings in double quotes. Values can be strings, numbers, booleans, null, arrays, or objects. No trailing commas or comments allowed.
JSON is commonly used for API responses, configuration files, data storage, and communication between web servers and clients.
Use our "Try to Fix" feature to automatically correct common JSON errors like single quotes, trailing commas, and unquoted keys.
