What type of data can be represented in a JSON file?

A JSON (JavaScript Object Notation) file is designed to represent structured data formats. It allows for the representation of data in a clear and organized way, utilizing key-value pairs which can be nested within each other to create complex data structures like arrays and objects. This format is text-based and integrates easily with various programming languages, making it ideal for data interchange between systems.

Structured data formats in JSON typically include numbers, strings, Booleans, arrays, and objects. JSON is particularly useful for APIs and configuration files, where data needs to be both human-readable and machine-readable. Its structured nature means that users can easily understand the relationships between different pieces of data within the file.

In contrast, options that suggest only strings, unstructured data formats, or binary data miss the scope of what JSON can accommodate. JSON is primarily focused on structured data representation, which is why it is widely used in web services and applications for data serialization and communication.
