Run this macro:

Sub Dup()
    Dim r As Long
    Dim m As Long
    Application.ScreenUpdating = False
    m = Range("A" & Rows.Count).End(xlUp).Row
    For r = m To 1 Step -1
        Range("A" & r).EntireRow.Copy
        Range("A" & r + 1).EntireRow.Insert
    Next r
    Application.CutCopyMode = False
    Application.ScreenUpdating = True
End Sub
