About JSON Formatter
A JSON formatter is a tool that takes raw JSON data and formats it with proper indentation and line breaks for better readability. It also validates the JSON syntax to catch errors before they cause problems.
JSON (JavaScript Object Notation) is the most common data format for APIs and web applications. When debugging or working with JSON data, properly formatted output makes it much easier to understand the structure and find specific values.
