About this tool

Realistic fake data is essential for seeding databases, testing UIs and prototyping — real data is sensitive and often unavailable early on. This generator produces dummy datasets modelled on common shapes: users, e-commerce products, companies and fintech transactions, exportable as JSON, SQL inserts or CSV.

Because the data is realistic — plausible names, prices, dates and relationships rather than “test test test” — it exercises layouts and logic the way real data will, revealing formatting and edge-case issues before you have live records. Multiple export formats let you drop it straight into a database, a fixture file or a spreadsheet.

It runs in your browser, so it is instant and offline. Use it to seed a development database, populate a prototype, or generate fixtures for tests.

Frequently asked questions

What kinds of data can it generate?
Datasets modelled on users, e-commerce products, companies and financial transactions, with realistic values.
What formats can I export?
JSON, SQL insert statements and CSV, so the data fits database seeds, fixtures or spreadsheets.
Why use realistic mock data?
Plausible values exercise your UI and logic the way real data will, surfacing formatting and edge-case problems that placeholder text hides.
Is it generated locally?
Yes. It runs in your browser, so no data is uploaded and generation is instant.
