Hello Excellers and welcome back to another blog post in my #macromondays series. Today I want to go back to Excel Macro basics for a short time and discuss the fundamental and important differences between ActiveWorkbooks and ThisWorkbooks.
At the most basic level….
ActiveWorkbook – this is the workbook that is the topmost Excel window or the one that has the current focus.
ThisWorkbook – this is the workbook in which the macro is running.
Why Is This Important To Know?
It is vital to understand the difference between the difference between these two workbooks. It is doubly important not to mix them up if you are working in multiple workbooks at the same time. In particular, if you run a macro from one workbook accidentally when another workbook is currently active. If you are referring to or using a VBA Range or VBA Cell directly, then this can have far-reaching and disastrous effects.
Explaining The Difference ActiveWorkbook vs ThisWorkbook
The active workbook refers to the workbook that is currently in focus and not the workbook that is visible to the user. Users can have multiple workbooks open and display them side by side on the screen. The active workbook is the only one that is currently selected. users can only have one workbook selected and that is the ActiveWorkbook. Below is a direct explanation from Microsoft.
In contrast, ThisWorkbook simply refers to the workbook that the VBA code is actually executing. Below is a direct explanation from Microsoft.
