 title: What is JSON Schema?
 ---
 JSON Schema is a declarative language for annotating and validating JSON documents' structure, constraints, and data types. It provides a way to standardize and define expectations for JSON data.

 ## How does JSON Schema work?
 
-When it comes to data exchange, JSON Schema stands out as a powerful standard for defining the structure and rules of JSON data. It uses various [keywords](https://json-schema.org/learn/glossary#keyword) to define the properties of your data.
+When it comes to data exchange, JSON Schema stands out as a powerful standard for defining the structure and rules of JSON data. It uses a set of [keywords](https://json-schema.org/learn/glossary#keyword) to define the properties of your data.
 
 While JSON Schema provides the language, validating a JSON [instance](https://json-schema.org/learn/glossary#instance) against a [schema](https://json-schema.org/learn/glossary#schema) requires a JSON Schema [validator](https://json-schema.org/implementations#tools). The JSON validator checks if the JSON documents conform to the schema.
 
 JSON validators are open-source and commercial tools that implement the JSON Schema specification. They make it very easy to integrate JSON Schema into projects of any size.

 ## Benefits of JSON Schema for Developers
 
 JSON Schema empowers developers in the following ways:
 
 * **Structured Data Description**: JSON Schema allows developers to describe the structure, constraints, and data types of existing JSON formats.
 * **Rule Definition and Enforcement**: By adhering to JSON schema constraints, it becomes easier to exchange structured data between applications as it maintains a consistent pattern.
 * **Produce clear documentation**: JSON Schema supports the creation of machine and human readable documentation.
-* **Extensibility:** JSON Schema offers high adaptability to developers' needs. Custom keywords, formats, and validation rules can be created to tailor schemas according to specific requirements..

 * **Data Validation:** JSON Schema ensures data validity through:
    * Automated Testing: Validation enables automated testing, ensuring data consistently complies with specified rules and constraints.
    * Improved Data Quality: By enforcing validation rules, JSON Schema aids in maintaining the quality of client-submitted data, reducing inconsistencies, errors, and potential security vulnerabilities.
