Frequently Asked Questions
Development test data and safety guidelines.
Are these emails and phone numbers real?
No, all generated emails use mock domains (like @example.com or @testmail.io) and phone numbers use designated dummy prefixes (like +1 (555)) to prevent accidental outreach to real people.
How is SQL format structured?
The SQL format generates complete, copy-pasteable INSERT INTO users (...) VALUES (...) statements. You can customize the target database table name in the generator settings.
Can I use this for production databases?
This tool is designed specifically for testing, local development, staging tests, and mockups. For large-scale production load tests, a backend-based streaming generator is recommended.
