What Random JSON does

Random JSON is a straightforward web utility that creates random JSON data structures for testing and development. Users select the desired complexity and structure, then generate a new JSON object with randomized key-value pairs. The output can be copied, downloaded, or exported for immediate use in front-end and back-end testing scenarios, providing a quick way to simulate API responses without manual coding.
