In One Minute : JSON

JSON (JavaScript Object Notation) is an open standard file format and data interchange format that uses human-readable text to store and transmit data objects consisting of attributevalue pairs and arrays (or other serializable values).

It is a common data format with diverse uses in electronic data interchange, including that of web applications with servers.
JSON is a language-independent data format.

It was derived from JavaScript, but many modern programming languages include code to generate and parse JSON-format data.
JSON filenames use the extension .json. Any valid JSON file is a valid JavaScript (.js) file, even though it makes no changes to a web page on its own.

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