JavaScript Object Notation (.json)

JSON stands for JavaScript Object Notation. It is a lightweight, human-readable format for storing and transporting data. JSON is often used when data is sent from a server to a web page and is "self-describing" and easy to understand.

JSON is an open standard file format and data interchange format that uses human-readable text to store and transmit data objects consisting of attribute-value pairs and arrays. It is a common data format with diverse uses in electronic data interchange.

It is language-independent and was derived from JavaScript. Many modern programming languages include code to generate and parse JSON-format data. JSON filenames use the extension ".json".

Douglas Crockford originally specified the JSON format in the early 2000s, and he and Chip Morningstar sent the first JSON message in April 2001.
