Use Cases: Who Should Use This Version?

Cons ❌

• Performance with Large Data: Can slow down on datasets above 50,000 rows × 100 columns (noticeable lag in Excel’s VBA engine).
• No Web/Mac Version (for 2021.2.2): This version is Windows-only (though newer XLSTAT versions now support Mac). 2021.2.2 relies on Excel for Windows.
• Steep Learning Curve for Advanced Tests: While basic stats are easy, advanced methods (e.g., mixed models, SEM) require reading the manual.
• No Real-Time Collaboration: Because it’s tied to Excel locally, simultaneous editing (via OneDrive/SharePoint) can break add-in links.
