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 is a very common format for sending data between web servers and clients.

Why do I need to format or 'beautify' JSON?

Often, JSON data is transmitted in a 'minified' state (without spaces or line breaks) to save bandwidth. This makes it very difficult for a person to read. A formatter adds indentation and line breaks to make the data structure clear and easy to debug.

Is my data safe with this online tool?

Yes. This JSON formatter is a client-side tool, meaning all validation and formatting happens directly in your browser. Your data is never sent to our servers, ensuring your information remains completely private.
