About

JSON (JavaScript Object Notation) is a lightweight, text-based data-interchange format built on two universal data structures: collections of name/value pairs and ordered lists of values. It is language-independent yet uses conventions familiar to C-family programmers, making it easy for both humans and machines to read, write, parse, and generate. The site serves as the official reference and specification page for the JSON format.

Problem

Developers need a simple, universal format to exchange structured data between different systems and programming languages.

For

software developers and systems that need to exchange structured data

How it works

JSON encodes data as human-readable text using two structures — key/value pair objects and ordered arrays — that map naturally to data types in virtually all modern programming languages.
