Maximum limits of memory storage and file size for Data Model workbooks

32-bit environment is subject to 2 gigabytes (GB) of virtual address space, shared by Excel, the workbook, and add-ins that run in the same process. A data model’s share of the address space might run up to 500 – 700 megabytes (MB), but could be less if other data models and add-ins are loaded.

64-bit environment imposes no hard limits on file size. Workbook size is limited only by available memory and system resources.

Beginning with Excel 2016, Large Address Aware functionality lets 32-bit Excel consume twice the memory when users work on a 64-bit Windows operating system. For more information, see Large Address Aware capability change for Excel.
