Why Do You Need 5,000 Rows?
Excel Performance
Dashboards often crash with large data. Use this to test if formulas like XLOOKUP or SUMIFS slow down your workbook.
Software QA Testing
Building a SaaS or CRM? Simulate what happens when a user uploads a massive list. Check if your database times out.
GDPR Compliance
Never use real data for testing. This tool creates Synthetic Data—100% compliant and safe to share in screen recordings.
