JSON formatter

With the JSON formatter tool , you can easily make JSON data readable and check for errors. JSON (JavaScript Object Notation) is widely used for data exchange between applications, APIs, and web services. Raw JSON is often difficult to read, especially when everything is on a single line.

This tool helps you automatically format JSON with clear indentation and structure.
