Difference Between 32-bit and 64-bit Office
The primary benefit of using Office 64-bit instead of Office 32-bit, is the amount of available memory. With 32-bit Office, the application can only use 2GB of RAM memory, but with 64-bit Office there is no limit. This can be extremely useful when working in Excel with large data sets or when working with Word documents or PowerPoint presentations full of rich media (videos, animations, pictures, etc..). There is no direct benefit to using 32-bit Office over 64-bit Office. The only potential benefit is compatibility issues (see below).

Should I use 32-bit or 64-bit Office?
Office 64-bit can only be installed on machines running 64-bit Windows. Office 32-bit can be installed on machines running both 64-bit and 32-bit Windows. So should you choose 64-bit or 32-bit? Starting with Office 2019, Microsoft changed the default installation version from 32-bit to 64-bit. So Microsoft recommends using the 64-bit version.

Reasons to choose the 64-bit version
Computers running 64-bit versions of Windows generally have more resources such as processing power and memory, than their 32-bit predecessors. Also, 64-bit applications can access more memory than 32-bit applications (up to 18.4 million Petabytes). Therefore, if your scenarios include large files and/or working with large data sets and your computer is running 64-bit version of Windows, 64-bit is the right choice when:

Reasons to choose the 32-bit version
64-bit Windows 10 with ARM-based processor
32-bit operating system with an x86 (32-bit) processor
Less than 4 GB RAM

Can I Install Both 32-bit and 64-bit Office?

Microsoft States that installing both 32-bit and 64-bit versions of Office on the same computer is not possible. However, it is possible, but a bit complicated

1. Install 64-bit version first
2. Then Install 32-bit version
3. 32-bit and 64-bit installs must be different versions (ex. Office 32-bit 2013, Office 64-bit 2019)
