- A JSON (JavaScript Object Notation) file is a lightweight, text-based, human-readable format used for data interchange. It is designed to store and transport data. JSON files use the .json file extension and are structured as a collection of name/value pairs, where the names are strings, and the values can be strings, numbers, arrays, or even other JSON objects. This format is widely used in web applications for exchanging data between a client and a server, as well as in configuration files.
