About this tool
Fake Data Generator
A fake data generator creates realistic but fictional records you can use to seed a database, populate a UI, or test an API without touching real user data. Pick from presets like names, emails, addresses, and dates, or describe the shape you need in plain English and let AI build the schema.
Generate as many rows as you need and export them as JSON or CSV in one click. It runs in your browser and is free on the HACKUP Free plan.
Frequently asked questions
Fake Data Generator FAQ
- What is fake data used for?
- Fake (mock) data is used to test software safely: seeding databases, filling out UI prototypes, load-testing APIs, and writing examples, all without exposing real personal information.
- What fields can it generate?
- Common presets include names, emails, phone numbers, addresses, dates, numbers, and booleans. You can also describe a custom schema in plain English and AI will generate matching fields.
- Can I export the data?
- Yes. You can export the generated dataset as JSON or CSV, ready to import into a database, spreadsheet, or test suite.
- Is the generated data real?
- No. All values are randomly generated and fictional. They are designed to look realistic but do not correspond to real people.
