Determining How Many Windows are Open

Written by Allen Wyatt (last updated May 21, 2025)
This tip applies to Excel 2007, 2010, 2013, 2016, 2019, and 2021

It is sometimes helpful for your macro to know how many Excel workbook windows are open at any given time. For instance, you might want your macro to only run if there is a single window open, or you might even require there to be two windows open. Either way, you need to check how many there are.

You determine the number of open windows by using the Count property of the Windows object. This is done using the following syntax:

X = Windows.Count

After executing the line, X is equal to the number of open windows.

Note:
