JSON

JSON, short for JavaScript Object Notation, is a text format for representing structured data as key–value pairs and ordered lists. It has become the default way that web services exchange data because it is easy for both people and programs to read. A JSON document is built from a small set of types: objects (collections of named values in curly braces), arrays (ordered lists in square brackets), strings, numbers, the booleans true and false, and null. Its strictness is part of its appeal — keys must be double-quoted, no trailing commas are allowed, and comments are not permitted — which keeps documents unambiguous but also makes small typos the usual cause of parse errors.
