Summarize this article for a 10 year old


JSON (JavaScript Object Notation, pronounced /ˈsən/; also /ˈˌsɒn/) is an open standard file format and data interchange format that uses human-readable text to store and transmit data objects consisting of attribute–value pairs and arrays (or other serializable values). It is a common data format with diverse uses in electronic data interchange, including that of web applications with servers.

Douglas Crockford originally specified the JSON format in the early 2000s.[1] He and Chip Morningstar sent the first JSON message in April 2001.
