Mock Data Generator

What is the Mock Data Generator?

This tool allows you to quickly create large sets of realistic dummy data for testing your applications or filling out database schemas.

How to Use

1. Add fields and define their types (String, Number, Boolean, UUID, Date).
2. If you select Object or an Array of Object, you can seamlessly add child properties (nested fields) inside them.
3. If you select Number, you can specify a uniform Range (min/max bounds).
4. Select the total number of root records, and click Generate.
5. Export the resulting generated data as JSON or CSV.

Terminology

• Object: A clustered item that holds sub-fields (key-value pairs) inside it.
• Array: Structured lists. You can define what type of items the list holds (e.g., Array of Number, Array of Object).

Common Use Cases

• Generating thousands of dummy user rows to test UI pagination rendering speeds.
• Creating complex, deeply nested JSON mock payloads to develop a frontend app before the backend API is ready.

Limitations / Notes

• To prevent browser crashes, the maximum generation limit is capped at 10,000 root items per request.

Security

All data generation happens directly in your browser using local randomization arrays. No network requests are made to fetch dummy data, ensuring absolute security and blazing-fast initialization.
