JSON (JavaScript Object Notation) is a lightweight, human-readable data interchange format. It is widely used for transmitting data between web servers and web applications, configuring software, and storing structured data. JSON uses key-value pairs and arrays, making it both easy for humans to read and easy for machines to parse.
Minified or machine-generated JSON is often compressed into a single line with no whitespace, making it nearly impossible to read. Formatting (or "beautifying") JSON adds proper line breaks and indentation, making the structure immediately visible. This is essential for debugging API responses, reading configuration files, and reviewing data structures.
