Odd and Even Rows
I had a large spreadsheet with over 1600 rows of information that I wanted to highlight alternating sections. If the first row of the section is an Odd number, color to background; otherwise, leave default.
Sub MakPretty()
Dim X As Long
Application.ScreenUpdating = False
For X = 5 To 1648 Step 3 'My rows are in groups of 3
Cells(X + 2, 13) = "=" & Cells(X + 2, 12).Address & "/34"
If Len(Cells(X, 1)) > 0 Then
Cells(X, 1).Interior.ColorIndex = 6
End If
Select Case X Mod 2 'If the row is not divisible by 2 i.e. Odd
Case 1
Range(Cells(X, 2), Cells(X + 2, 13)).Select
Selection.Interior.ColorIndex = 40
Case Else
End Select
Next
Application.ScreenUpdating = True
End Sub
It happened that the 3^{rd} row of each section needed a computation in the last column.For the 1600 or so rows, the process is almost instantaneous.
