What is JSON?

JSON (JavaScript Object Notation) is a lightweight, text-based data interchange format that's easy for humans to read and write, and easy for machines to parse and generate. Originally derived from JavaScript, JSON is now language-independent and used universally across modern web development, APIs, and data storage.

JSON represents data as key-value pairs wrapped in curly braces {}, with support for nested objects and arrays. This simple structure makes JSON the de facto standard for web APIs, configuration files, and data exchange between systems.

JSON Example

{
  "name": "John Doe",
  "age": 30,
  "email": "john@example.com",
  "isActive": true,
  "roles": ["admin", "user"]
}

Why JSON?

  • Human-readable and easy to debug
  • Supported by all programming languages
  • Lightweight (smaller than XML)
  • Native JavaScript support
  • Perfect for APIs and web services
