👁️ Table Preview
⚠️ This data is fake, and that's the point. Names, emails and addresses are assembled from generic word lists and are not real people. Never populate a staging or demo environment with a copy of production data — that's how personal information ends up somewhere it was never meant to be. Everything here is generated in your browser and never uploaded.
HOW IT WORKS
Realistic Enough To Find Real Bugs
Good test data isn't just filler — it's shaped like the real thing so it surfaces the bugs real data would. Names here vary in length so your layout gets tested against both "Li Wu" and a long hyphenated surname; emails are derived from the generated name so they look plausible rather than random; dates fall in sensible ranges rather than the year 47000. Export formats cover the usual paths: JSON for API stubs and fixtures, CSV for spreadsheets and bulk import, SQL inserts for seeding a database directly, and a TypeScript interface when you want the type rather than the values. Everything is generated locally, so you can safely use it for commercial work without anything leaving your machine.

Mock Data FAQ
Could any of this data match a real person?
Names are assembled by combining common first and last names, so a combination could coincidentally match someone — but nothing here is drawn from any real dataset, and emails use the reserved example.com domain, which can never receive mail. Treat it as fictional, because it is.
Can I use this for commercial projects?
Yes. It's generated on your machine from generic word lists, with no licensing restrictions and nothing transmitted anywhere.
Why example.com for emails?
Because RFC 2606 reserves it precisely so test data can't accidentally send mail to a real address. Test data that reaches a stranger's inbox is a genuine and surprisingly common incident.
How many rows can I generate?
Up to 1,000 per run. Past that, browser rendering becomes the bottleneck rather than the generation, and a script in your own language is a better fit.
Are the SQL inserts safe to run directly?
Values are escaped for single quotes, but always review generated SQL before running it against anything you care about — and never against production. The table name in particular is inserted as you type it.
