What is JSON?

JSON (JavaScript Object Notation, pronounced /ˈdʒeɪsən/; also /ˈdʒeɪˌsɒn/) 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 very common data format, used by a diverse range of applications. One example are web applications that communicate with a server using JSON-encoded strings.

JSON was derived from JavaScript, but many modern programming languages include code to generate and parse JSON-format data. JSON filenames use the extension .json. The JSON mime-type is: application/json. More about JSON you could find on json.org and Wikipedia

What else is JSON used for?

JSON-LD is the abbreviation of "JavaScript Object Notation for Linked Data". It is a concept for linking JSON data and exchange them between web services and applications. JSON-LD uses standardised semantic identifiers like @id, @url or @name from schema.org for field names. The file extension of JSON-LD is .jsonld and the mime-type is application/json+ld.

JWT or "JSON Web Tokens" are an open, industry standard RFC 7519 method for representing claims securely between two parties. The tokens are signed either using a private secret or a public/private key.

JSON-RPC is a remote procedure call protocol encoded in JSON. It is similar to the XML-RPC protocol, defining only a few data types and commands. JSON-RPC allows for notifications (data sent to the server that does not require a response) and for multiple calls to be sent to the server which may be answered asynchronously.
