What types of fake data are generated?

The generator produces realistic values based on field names: fields named "email" get email addresses, "name" gets a full name, "date" gets an ISO date string, "url" gets a URL, and so on. Unknown fields get random values for their type.

Can I generate arrays of objects?

Yes. Set a field type to "array" and configure the item type and count. The generator fills the array with the specified number of mock items.

Is the output valid JSON?

Yes. The output is always valid JSON that you can copy directly into your tests, Postman mock server, or frontend prototype.
