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.

Fast & Lightweight

JSON is more compact than XML and faster to parse, making it ideal for web applications.

Human Readable

Easy to read and write by humans, with a clean and simple syntax structure.

Language Independent

Supported by virtually all programming languages and platforms.

JSON Syntax Example

  "person": {
    "name": "Alice Johnson",
