What Is a JSON Formatter?
A JSON Formatter is an online tool that takes JavaScript Object Notation (JSON) data and presents it in a structured, readable format. JSON is widely used for APIs, web applications, configuration files, data exchange, and software development. When JSON is compressed into a single line or contains inconsistent formatting, it can be difficult to read and troubleshoot.
A JSON formatter adds indentation and line breaks to make the structure of objects and arrays easier to understand. A JSON validator can also check the syntax and report errors when the supplied data is not valid JSON.
