32-bit vs 64-bit: Which to Choose?
Choose 32-bit if:
- You use older add-ins that require 32-bit

Choose 64-bit (Recommended):
- You work with very large Excel files (>2 GB)
- Your system has 4 GB+ RAM
- You use PowerPivot, Power View, or large 3D models
- Better overall performance and security
Note: Unlike Office 2016, Microsoft recommends the 64-bit version of Office 2019 for most users. Only choose 32-bit if you have specific compatibility requirements.
