Faster code to delete character "#"

Hello,

In my sample (sheet Turnover) I use the below mentioned code to delete the charahter "#" from column M (from some thousand cells), the code is working fine just too slow for me, do you have faster solutions?

Sub test()
Dim c As Range

Application.ScreenUpdating = False

   For Each c In Worksheets("Turnover").Range("M9:M2294")
   With c
   If Left(.Value, 1) = "#" Then .Value = Left(.Value, Len(.Value) - 1)
   End With
   Next c
   
Application.ScreenUpdating = True

End Sub

The sample file has been added to this thread.

Thanks in advance your help!
