I wish to remove an element from the array that contains " " or "" I know it will involve a redim maybe a preserve too but not sure how to remove at the right place

so far:

  For index = LBound(AliasArray) To UBound(AliasArray)
            If AliasArray(index) = " " Or AliasArray(index) = "" Then remove that element
           
       
        Next index

You can use a temporary array.

Option Explicit

Sub EE()

Dim arr As Variant
Dim arrTmp() As Variant
Dim x As Long, counter As Long

arr = Array(1, 2, 3, " ", 4)

For x = LBound(arr) To UBound(arr)

    If Not (arr(x) = "" Or arr(x) = " ") Then
    
        ReDim Preserve arrTmp(counter)
        
        arrTmp(counter) = arr(x)
        
        counter = counter + 1
        
    End If
Next x

arr = arrTmp

End Sub

that looks great could you teach me about this part :

arr = Array(1, 2, 3, " ", 4)

i can see its making arr equal to array but the bits within the brackets i am not sure about

Sorry, that is just me creating the initial array with some elements to test. If your AliasArray already has elements then you can remove the line. Something like this.

Option Explicit


Dim arrTmp() As Variant
Dim x As Long, counter As Long



For x = LBound(AliasArray) To UBound(AliasArray)

    If Not (AliasArray(x) = "" Or AliasArray(x) = " ") Then
    
        ReDim Preserve arrTmp(counter)
        
        arrTmp(counter) = AliasArray(x)
        
        counter = counter + 1
        
    End If
Next x

AliasArray= arrTmp

How are you creating the array in the first place?

If it's through code using Redim etc then perhaps you could add something to the code that creates the array to exclude the values/strings/whatever you don't want in the array.
