Sub InsertLines()
Dim wks As Worksheet
Dim rng As Range

Set wks = ActiveSheet

With wks
Set rng = .Cells(Rows.Count, "A").End(xlUp)
Do While rng.Row 1
rng.EntireRow.Insert
rng.Offset(-1, 0).Value = "'========="
Set rng = rng.Offset(-2, 0)
Loop
End With
End Sub

I have an excel spreadsheet with 20k rows of data. Want to add a row

"=========" without the quotes. Can someone suggest a macro to do
this?

Thanks.
