JSON (canonically pronounced /ˈdʒeɪsən/ JAY-sən; sometimes JavaScript Object Notation) is an open standard format that uses human-readable text to transmit data objects consisting of attribute–value pairs. It is the most common data format used for asynchronous browser/server communication (AJAJ), largely replacing XML which is used by AJAX.
JSON is a language-independent data format. It derived from JavaScript, but now code to generate and parse JSON-format data is available in many programming languages. The official Internet media type for JSON is application/json
. The JSON filename extension is .json
.
The JSON format was originally specified by Douglas Crockford. It is described by two competing standards, RFC 7159 and ECMA-404. The ECMA standard describes only the allowed syntax, whereas the RFC also provides some semantic and security considerations.
A typical mashup fetches JSON-format data from several different web servers using an Open API.
JSON grew out of a need for stateful, real-time server-to-browser communication without using browser plugins such as Flash or Java applets, which were the dominant methods in the early 2000s.
