JSON is a lightweight format for storing and transporting data. JSON 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 serialisable values). An excellent example of JSON use is structured data (rich results) used by search engines to present and collect information about internet websites.
Examples of JSON attribute-value pairs:
- @type – “WebPage”
- @id – “https://360webcare.com/dictionary/api-application-programming-interface/#webpage”
- datePublished – “2021-07-04T01:20:29+00:00”, etc. – look at the picture below
It is a standard data format with a diverse range of functionality in data interchange, including communication of web applications with servers.
Douglas Crockford initially specified the JSON format in the early 2000s.
