JSON (an acronym for JavaScript Object Notation).
The JSON format is often used for serializing and transmitting structured data over a network connection. It is primarily used to transmit data between a server and web application, serving as an alternative to XML.

Despite its relationship to JavaScript, it is language-independent, with parsers available for virtually every programming language.

The JSON filename extension is .json.
