JSON (JavaScript Object Notation)

What is JSON?

JSON is a text-based data format that is used to represent and transfer structured data. It is easy to read, both for humans and machines, and is often used in web APIs, databases and configuration files. JSON is based on simple key-value pairs and supports nested data structures such as arrays and objects.

Advantages and areas of application

JSON is widely used due to its simplicity and platform independence. It enables efficient data transfer between servers and web applications and has replaced older formats such as XML in many areas. Typical applications include REST APIs, configuration of software projects and the storage of data in NoSQL databases such as MongoDB.
