What is JSON?
JSON (JavaScript Object Notation) is a lightweight data-interchange format that is easy for humans to read and write, and easy for machines to parse and generate. It's widely used in web APIs, configuration files, and data storage.
Why Format JSON?
Properly formatted JSON is much easier to read, debug, and maintain. Our free JSON formatter adds indentation and line breaks to make nested structures clear, while also validating your JSON syntax to catch errors early.
