Try the macro below.
Replace 99 with the last row you want to leave (has to be multiple of 3)

Sub DelRow()
Application.ScreenUpdating = False
For i = 99 To 3 Step -3
Range("A" & i & ":A" & i + 1).Select
Selection.EntireRow.Delete
Next i
Application.ScreenUpdating = True
End Sub

Hello:

I need a macro to delete every other rows starting from row2. For example
Col B
Row2: Test1-a
Row3 Test1-b
Row4 Test1-c
Row5: Test2-a
Row6: Test2-b
Row7: Test2-c

In other words, I'd like the macro to delete row 3-4 (b-c) and 6-7 (b-c),
and so on

Thanks again,
