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. Our JSON formatter tool helps developers work with JSON data more efficiently by providing formatting, validation, and minification capabilities.
Whether you're working with API responses, configuration files, or data structures, properly formatted JSON is essential for readability and debugging. This tool processes all JSON data entirely in your browser, ensuring your data never leaves your device and remains completely private and secure.
The tool supports all standard JSON features including nested objects, arrays, strings, numbers, booleans, and null values. It can handle JSON of any complexity, from simple key-value pairs to deeply nested structures with multiple levels of indentation.
