What Is JSON?
It is a text format that is used to transmit data between a server and a web application, as well as between different parts of a web application. JSON is commonly used in web development for tasks such as sending and receiving data between a server and a client-side web application, or for storing data in a format that can be easily exchanged between different systems.
JSON data is organized into key-value pairs, where keys are strings and values can be strings, numbers, arrays, objects, booleans, or null.
See the JSON specification for more information.
