Introduction - Application.ScreenUpdating = False

Prevent your screen from updating until your Excel macro is finished with Application.ScreenUpdating=False. The Application.ScreenUpdating property is useful when running macros that jump from cell to cell, sheet to sheet, and workbook to workbook.

Setting the Application.ScreenUpdating to False stops your screen from flickering (refreshing) as your macro runs. It can be used for other applications, but I find it most useful for Excel.

Example - Application.ScreenUpdating = False

Screen Updating Demonstration

Sub ScreenUpdatingDemo()
Application.ScreenUpdating = False
For j = 1 To 10
    For i = 1 To 25
        Selection = i
        Selection.Offset(1, 0).Select
    Next i
    Selection.Offset(-25, 1).Select
Next j
Application.ScreenUpdating = True
End Sub

Tutorial - Application.ScreenUpdating = False

This demo uses Selection.Offset to forcefully change the selected cell in Excel. I recommend disabling ScreenUpdating anytime you are manually selecting cells or worksheets. Play around with the Application.ScreenUpdating property to prove it works.

Change False to True in Line 2 to see what happens when you don’t disable screen updating. Your screen will show each action your VBA code performs.

Displaying each step slows your macro down. It’s a good practice to disable screen updating to decrease total run time. Don’t forget to set your ScreenUpdating property back to True when you’re done.

Application Ideas - Application.ScreenUpdating = False

The silly code I presented in the ScreenUpdating Demonstration just numbers cells. Better uses for Application.ScreenUpdating=False are presented below:

  1. Adding new Worksheets
  2. Manipulating Word Documents from Excel
  3. Sending email from Excel
  4. Switching between Excel Sheets.
  5. Opening new Excel Workbooks.
  6. Switching between pages in Word.
