Where does the random data come from?

Built-in arrays of first names, last names, cities, companies and jobs — combined with crypto.getRandomValues for IDs, ages and numbers.

Is the data realistic?

Reasonably — names are real first/last names from common English-speaking countries, emails follow common patterns, addresses use real city names. But the data is fake and shouldn't be used to impersonate anyone.

Can I get the output as SQL?

Yes — SQL INSERT statements with proper string escaping. Useful for seeding test databases.

Is the data uploaded?

No. Generation happens entirely in your browser.
