JavaScript Object Notation (JSON) is an open-standard file format. JSON uses human-readable text to transmit data objects consisting of name–value pairs, and array data types (or any other serializable value). JSON is a very common data format used for asynchronous browser–server communication, including as a replacement for XML.
