JSON, abbreviated from JavaScript Object Notation, is an open standard file format for storing human-readable structured data as key-value pairs and arrays. It is a very common format in web applications and data interchange uses. JSON, as a lightweight, text-based, human-readable format, is being supported by many programming languages. In recent years, JSON has become a popular alternative to XML.
