Sub Macro9()
    Range("Table57[Weld Done]").Select
    Selection.Replace What:="0/1/1900", Replacement:="", LookAt:=xlPart, _
      SearchOrder:=xlByRows, MatchCase:=False, SearchFormat:=False, _
      ReplaceFormat:=True, FormulaVersion:=xlReplaceFormula2
    Range("Table57[[#Headers],[Weld Done]]").Select
End Sub
I used the Replace function to replace default date 0/1/1900 with "blank" & it worked. So I recorded the workflow using VBA macro recording function & it gives coding as above.
When I try to use the macro, the value remains as default date 0/1/1900.
