JSON is a simple data format, but its simplicity is not the only thing that makes it a leading standard for exchanging data among web services and applications. The most important reason for its popularity is the fact that the JSON format is native for many programming languages, such as JavaScript. They can generate and consume JSON data natively, without serialization. One of the biggest problems in software development in recent years is object-relational impedance. The JSON data format is flexible and self-describing and allows you to use it effectively without defining a strict schema for data, which XML might need. This allows for the quick integration of data.
