JSON (JavaScript Object Notation) is a lightweight data format used to represent and exchange structured information between applications. It organizes data using objects, arrays, key-value pairs, numbers, text, and logical values, making information easy for both software and people to read. Because it is simple and supported by many programming languages, JSON is widely used for transferring data between web applications, services, and devices.
For example, an online shopping application can use JSON to send product details such as names, prices, availability, and specifications between its website and backend services. JSON is useful for APIs, configuration files, web applications, cloud services, and data exchange. Its simple structure, broad compatibility, and relatively compact format make it a practical choice for connecting different software systems.
