JSON (JavaScript Object Notation) is a lightweight data-interchange format. JSON is used for exchanging data between applications and different environments.

Example of a JSON Document

A JSON document looks like this:

JSON is based on a subset of the JavaScript Programming Language, Standard ECMA-262 3rd Edition - December 1999.

JSON is a text format that is completely language independent but uses conventions that are familiar to programmers of the C-family of languages, including C, C++, C#, Java, JavaScript, Perl, Python, and many others. These properties make JSON an ideal data-interchange language.
