💡 All data is randomly generated in your browser — no rows limit, no account, nothing uploaded. Names, companies, and addresses are fictional and any resemblance to real data is coincidental.

UI prototyping tips

🎨

Real-looking names, jobs, and dates make a prototype far more convincing than "lorem ipsum" everywhere.

📐

Generate just enough rows to test layouts — long names and empty states reveal design issues early.

🔁

Regenerate to see how your UI handles different value lengths and distributions.

🔒

All placeholder data is fictional and made on your device.
