JSON
JSON (an acronym for JavaScript Object) is a lightweight text-based open standard designed for human-readable data interchange. It is derived from the JavaScript programming language for representing simple data structures and associative arrays, called objects. Despite its relationship to JavaScript, it is language-independent, with parsers available for most programming languages.
The JSON format was originally specified by Douglas Crockford, The official Internet media type for JSON is application/json. The JSON filename extension is .json.

Efficiency
JSON is primarily used for communicating data over the Internet, but has certain inherent characteristics that may limit its efficiency for this purpose. Most of the limitations are general limitations of textual data formats and also apply to XML and YAML. For example, despite typically being generated by an algorithm (by machine), parsing must be accomplished on a character-by-character basis. Additionally, the standard has no provision for data compression, interning of strings, or object references. Compression can, of course, be applied to the JSON formatted data (but the decompressed output typically still requires further full parsing for recognizable keywords, tags and delimiters).
