About mock data
A mock data generator creates realistic-looking fake data — names, emails, addresses, numbers and more — for testing and development. Choose the fields and how many rows you need, then export the result as JSON or CSV. It is perfect for seeding databases, building UI prototypes and testing APIs without using real personal data. Everything is generated in your browser.
How Mock Data works
How to generate mock data
- Pick the fields you need (name, email, address, number, date, and more).
- Set how many rows to generate.
- Copy or download the result as JSON or CSV.
Why use fake data
Testing with realistic but fake data lets you build and demo features without exposing real customer information — safer for privacy and compliance, and easy to regenerate.
Use it anywhere
Seed a development database, fill a table or form prototype, or feed a test API. JSON and CSV export work with almost any tool or language.
