Random Data Generator
Fake rows for testing, as JSON, CSV or SQL. Never real people.
Generated on your device. No real data is involved at any point.
Filling a table with test rows is the sort of thing everyone does badly once. Typing names by hand produces twenty rows of "test test", and copying a real customer export into a development database is a mistake that people are still apologising for years later.
More about Random Data Generator
Everything generated here is fabricated and, more importantly, unable to reach anybody. Email addresses use the domains reserved by RFC 2606, which can never be registered by anyone; phone numbers use a range set aside for drama and documentation. That distinction is what separates test data from an accident: a generated address cannot land in a real inbox even if your staging environment starts sending mail.
Vietnamese names are the default here, in Vietnamese order, with their marks. That matters more than it sounds. A product tested only against "John Smith" never finds out that its column is too narrow, that its sort order is wrong, or that its font clips the marks off "Nguyễn Thị Ánh Nguyệt" — and it finds out on launch day instead.
Output comes as JSON, CSV or SQL INSERT statements. Each one is escaped for its own format: commas and quotes are handled in CSV, single quotes are doubled in SQL, and the JSON and SQL output both carry a line saying the data is fabricated.
- Emails at RFC 2606 reserved domains, which can never reach a real inbox
- Phone numbers from a range set aside for fiction
- Vietnamese names in Vietnamese order, with their tone marks
- Nine field types: names, emails, phones, addresses, UUIDs, numbers, dates and more
- JSON, CSV and SQL output, each escaped correctly for its own format
- A fabricated-data notice in the output itself, where the format allows

Questions
Can these email addresses reach anyone?
No. They use the domains reserved by RFC 2606, which can never be registered, so mail to them goes nowhere.
Are the phone numbers real?
No. They come from a block set aside for drama and documentation, so they cannot ring a real person.
Why default to Vietnamese names?
Because testing only with Western names hides the problems that appear on launch day: narrow columns, wrong sort order and clipped tone marks.
Is the CSV output safe to import?
Yes. Cells containing a comma or a quote are quoted and escaped per RFC 4180, so a name with a comma does not shift every later column.
Can I use this data in production?
No, and it is labelled so nobody does by accident. It is for filling test tables and demos, nothing else.
