This article aims to equip you — whether you’re an end user, IT admin, or developer — with actionable tips to enhance the speed and responsiveness of your VBA macros.
1. Streamline VBA by Disabling Unnecessary Features
When aiming to speed up VBA code, consider turning off non-essential features such as animations, automatic calculations, screen updating, and events during macro execution.
Sub SwitchOff(bSwitchOff As Boolean)
Dim ws As Worksheet
With Application
If bSwitchOff Then
‘ Turn OFF
lCalcSave = .Calculation
bScreenUpdate = .ScreenUpdating
.Calculation = xlCalculationManual
.ScreenUpdating = False
.EnableAnimations = False
For Each ws In ActiveWorkbook.Worksheets
ws.DisplayPageBreaks = False
Next ws
Else
‘ Turn ON
If .Calculation <> lCalcSave And lCalcSave <> 0 Then .Calculation = lCalcSave
.ScreenUpdating = bScreenUpdate
.EnableAnimations = True
End If
End With
End Sub
Sub Main()
SwitchOff(True) ‘ Turn off features
‘ Execute your processing here
SwitchOff(False) ‘ Turn features back on
End Sub
