How to use
- Pick how many rows and which fields you need.
- Choose Vietnamese or English name and address style.
- Generate, then copy as CSV or JSON, or download the CSV.
- Keep the seed with the test: the same seed rebuilds exactly these rows.
Features
- Vietnamese names, addresses and mobile prefixes that look right.
- Seeded output, so a fixture can be reproduced from the seed alone.
- Every email on a reserved example domain — test mail cannot reach a stranger.
- CSV and JSON, with proper quoting for values containing commas.
- Runs entirely in your browser.
Frequently asked questions
- Why does the seed matter?
- Because a test that fails on a Tuesday should fail the same way on a Wednesday. With a seed recorded next to the test, the exact rows can be rebuilt months later; without one, you are debugging from a screenshot of data that no longer exists.
- Are these real people?
- No. Names are assembled from common components, addresses use real street names with invented numbers, and every email address lands on example.com, example.org or example.net — domains reserved by RFC 2606 precisely so that test mail cannot be delivered to anyone. That last part matters: the classic accident is a staging environment mailing thousands of made-up addresses at a real domain.
- Are the phone numbers real?
- They follow the right shape — Vietnamese mobiles begin 03, 05, 07, 08 or 09 — so validation and formatting can be tested. Do not dial them; a correctly shaped number can belong to somebody.
