When working with Excel, especially in larger files or when executing lengthy macros, optimizing performance is crucial. One of the simplest yet most effective ways to improve the efficiency of your macros is by turning off screen updating. This not only speeds up the execution of your code but also enhances the user experience by preventing screen flickering. In this guide, we'll explore how to turn off screen updating in Excel macros, share helpful tips, advanced techniques, and highlight common mistakes to avoid.
Why Turn Off Screen Updating?
Turning off screen updating while your macro is running allows Excel to run the code faster. When screen updating is disabled, Excel does not refresh the screen with every action, which can slow down the macro execution significantly.
Benefits of Disabling Screen Updating
- Speed: Macros run significantly faster since Excel isn't drawing the screen.
- Reduced Flicker: Users don’t see the intermediate steps of the macro, leading to a cleaner execution.
- Increased Focus: It allows users to focus on the results without distractions.
How to Turn Off Screen Updating
Turning off screen updating in your macro is straightforward. Here’s how to do it:
Step-by-Step Tutorial
-
Open your Excel workbook: Make sure your VBA editor is accessible.
-
Access the VBA editor: Press
ALT + F11
to open the VBA editor. -
Find your macro: Locate the macro you want to edit in the left pane.
-
Insert the code to disable screen updating: At the beginning of your macro, add the following line:
Application.ScreenUpdating = False
-
Insert the code to enable screen updating: At the end of your macro, add:
Application.ScreenUpdating = True
Example Code
Here’s a simple example of how it looks in practice:
Sub MyMacro()
Application.ScreenUpdating = False
' Your code goes here
Application.ScreenUpdating = True
End Sub
This straightforward implementation will help ensure your macro runs as smoothly and quickly as possible!

Common Mistakes to Avoid
While turning off screen updating is generally helpful, there are some common pitfalls to watch out for:
-
Forgetting to Turn It Back On: Always ensure that
Application.ScreenUpdating
is set back toTrue
at the end of your macro. Failing to do so can leave Excel in a state where it doesn’t update the display. -
Not Testing Your Code: Before deploying a macro that disables screen updating, make sure to run it in a test environment first. This helps identify issues without affecting your main workbook.
-
Overusing in Small Macros: If your macro consists of just a few lines, the overhead of turning off screen updating might not be worth it. Use it mainly for longer processes.
Advanced Techniques
Combining with Other Performance Optimizations
Turning off screen updating is just one of the techniques you can use to improve your macro’s performance. Here are other strategies:
-
Disable Automatic Calculations: If your macro makes several changes to the workbook, you might want to turn off automatic calculations temporarily. Use:
Application.Calculation = xlCalculationManual
Don’t forget to set it back to automatic afterwards:
Application.Calculation = xlCalculationAutomatic
-
Disable Events: Prevent other macros from running by disabling events. Use:
Application.EnableEvents = False
And remember to enable them again:
Application.EnableEvents = True
Full Example Code
Here’s how you could combine all of these techniques into one macro:
Sub OptimizedMacro()
Application.ScreenUpdating = False
Application.Calculation = xlCalculationManual
Application.EnableEvents = False
' Your macro code here
Application.EnableEvents = True
Application.Calculation = xlCalculationAutomatic
Application.ScreenUpdating = True
End Sub
This structure helps ensure that your macro runs as efficiently as possible!
