JSON data files are files that contain data in the JSON format. These files typically have a ".json" extension and can be opened and read using any text editor or programming language that supports JSON.
JSON files consist of a collection of key-value pairs, where each key represents a field or attribute of the data, and each value represents the corresponding value for that field. JSON data can be nested, meaning that values can be arrays or objects that contain additional key-value pairs.
Here's an example of what a JSON file might look like:
{ "name": "John Doe", "age": 35, "email": "johndoe@example.com", "address": { "street": "123 Main St", "city": "Anytown", "state": "CA", "zip": "12345" }, "phoneNumbers": [ { "type": "home", "number": "555-555-1234" }, { "type": "work", "number": "555-555-5678" } ]} |
This JSON file represents a single object, which contains information about a person's name, age, email address, address, and phone numbers. The "address" field is itself an object, while the "phoneNumbers" field is an array of objects.
JSON files are commonly used for data storage and interchange in web applications, and can be easily parsed and manipulated using a variety of programming languages and tools.
