The most significant advantage of the 64-bit version is its ability to handle massive data sets. While a 32-bit application is limited to approximately 2 GB of virtual address space, a 64-bit application can access up to 18.4 million petabytes of memory. This is particularly beneficial for Excel users who work with gigantic spreadsheets, complex scientific calculations, or Power Pivot models. In Project, it allows for the handling of larger resource and task files, and in PowerPoint, it improves the management of large videos and high-resolution images.

: Includes the LongLong data type in VBA, which supports 64-bit memory addresses and larger integer values.
The most significant advantage of 64‑bit software is its ability to use more than 4 GB of RAM. A 32‑bit application is hard‑capped at 4 GB of addressable memory, and on many systems it can't even use the full 4 GB effectively. The 64‑bit edition of Office, by contrast, can access as much RAM as your computer has installed, making it far more capable when handling large workloads. For example, a 64‑bit Office installation can allocate massive amounts of memory to Excel when it works with extremely large spreadsheets, something a 32‑bit version cannot do.
