I'm using the following code to reformat dates in 3 different columns,
for example, Column T goes from 2070126 to 01/26/2007. What I'd like
to do is add something to it that will check each column first to make
sure it hasnt already been reformatted. Any ideas?


Sub CleanUp_Data_File()

Application.ScreenUpdating = False

With ActiveSheet

' ~~ Reformat Column P ~~
Columns("P:P").Insert
Range("P3:P" & Range("Q65536").End(xlUp).Row).FormulaR1C1 = _
"=MID(RC[1],5,2)&""-""&MID(RC[1],1,3)&""-""&MID(RC[1],8,4)"
Range("P3:P" & Range("P65536").End(xlUp).Row).Copy
Range("Q3").PasteSpecial xlPasteValues, , False, False
Columns("P:P").EntireColumn.Delete

' ~~ Reformat Column S ~~
Columns("S:S").Insert
Range("S3:S" & Range("T65536").End(xlUp).Row).FormulaR1C1 = _
"=MID(RC[1],4,2)&""/""&MID(RC[1],6,2)&""/""&""20""&MID(RC[1],
2,2)"
Range("S3:S" & Range("S65536").End(xlUp).Row).Copy
Range("T3").PasteSpecial xlPasteValues, , False, False
Columns("S:S").EntireColumn.Delete

' ~~ Reformat Column T ~~
Columns("T:T").Insert
Range("T3:T" & Range("U65536").End(xlUp).Row).FormulaR1C1 = _
"=MID(RC[1],4,2)&""/""&MID(RC[1],6,2)&""/""&""20""&MID(RC[1],
2,2)"
Range("T3:T" & Range("T65536").End(xlUp).Row).Copy
Range("U3").PasteSpecial xlPasteValues, , False, False
Columns("T:T").EntireColumn.Delete

End With

Application.ScreenUpdating = True

End Sub
