JSON Schema is a standard for describing and validating the structure, data types, and rules of JSON data. It defines what properties an object can contain, which fields are required, what values are allowed, and how nested data should be organized. Applications can use these rules to check whether JSON data follows the expected format before processing it, helping prevent errors and inconsistent information.
For example, an e-commerce API can use JSON Schema to require product data to include a name, price, and availability status in specific formats. Developers can validate incoming requests and responses automatically, making integrations more reliable. JSON Schema is useful for APIs, configuration files, data validation, software development, and automated testing, improving consistency and simplifying communication between different applications.
