Frequently Asked Questions

Can I control which columns are generated?

Yes — choose names plus types per column, or accept the default identity-style set of six columns.

Are generated emails safe to send to?

They follow valid syntax but mix real domains with example ones. Never email generated addresses.

Is the randomness cryptographically secure?

No — it uses standard Math.random, which is ideal for fixtures but not for secrets or lottery-style draws.
