What criteria determines if the column is not wanted?

Hi
not very elegant but

Sub removecolumns()
Dim ws As Worksheet
Dim columnarray As Variant
Dim arraysize As Integer, i As Integer

Application.ScreenUpdating = False
columnarray = Array(1, 3, 7, 8, 9)
arraysize = UBound(columnarray)

For Each ws In ActiveWorkbook.Worksheets
For i = arraysize To 0 Step -1
ws.Columns(columnarray(i)).Delete
Next i
Next ws
End Sub

Replace your array values with the columns you need to remove.
note: Array is 0 based so counting starts at 0. You run the delete
from right to left or you will delete coulmns you need to keep as
deletion will upset the column number.
regards
Paul
