javascript object notation

Short for JavaScript Object Notation, JSON is a data format for transmitting data from one place to another, most commonly between a server and a Web application. The JSON format was specified by Douglas Crockford.

JSON is based on the JavaScript programming language, but can be used in most other languages with a special JSON parser. It is an alternative to XML (extensible markup language) for storing, associating, and accessing data. Below is an example of valid JSON:

 "Name" : "Ed",
 "Career" : "Teacher"

Basically, JSON formats data into JavaScript objects and facilitates the use of name and value pairs, arrays, strings, and other data types. When this data is read by a JSON parser, it's converted into the appropriate data type in the programming language used for quick retrieval of data. When saving JSON data, the file extension used is .json.
