Sub RemoveEveryFifthRow()
Dim myRows As Long
Range("A1").EntireColumn.Insert
Range("A1").FormulaR1C1 = _
"=IF(MOD(ROW(),5)=0,""Trash"",""Keep"")"
myRows = ActiveSheet.UsedRange.Rows.Count
Range("A1").Copy Range("A1:A" & myRows)

.Copy
.PasteSpecial Paste:=xlValues

One way:


Sub DeleteEveryFifthRow()
Dim lRow As Long
lRow = Range("A65536").End(xlUp).Row
Do While lRow > 0
Cells(lRow, 1).EntireRow.Delete
lRow = lRow - 5
Loop
End Sub
