Identifying duplicate entries is fairly easy, see http://www.cpearson.com/excel/duplicat.htm#HighlightingDuplicates

However for a 200 whopper you deserve a bit more than just general instructions. Therefore:

a) What is your data structure ? Please paste a sample of your dataset.

b) Is this a one time job or a re-occuring house keeping job ?

c) Did you ever record a macro ?

Hi kwaichung

This code will move all duplicates to "Sheet2". It assumes your Column to check is Column A and the Column A has a heading.

To use it push Alt+F11 and go to Insert>Module, then paste in the code. Push Alt+Q to return to Excel and save. Now push Alt+F8, select "MoveDupes" and click run.



Sub MoveDupes()
Dim lLastRw As Long
Dim rMove As Range

lLastRw = Range("A65536").End(xlUp).Row

Columns(1).EntireColumn.Insert
   Range("A3:A" & lLastRw).FormulaR1C1 = _
        "=IF(AND(COUNTIF(R3C[1]:R7000C[1],RC[1])>1" _
        & ",COUNTIF(R2C:R[-1]C,RC[1])=0),RC[1],"""")"
       
Range("A3:A" & lLastRw) = Range("A3:A" & lLastRw).Value

Set rMove = Range("A3:A" & lLastRw).SpecialCells(xlCellTypeConstants)

rMove.Copy Destination:=Sheets("Sheet2").Range("A1")
rMove.EntireRow.Delete

Columns(1).EntireColumn.Delete

Set rMove = Nothing

End Sub




If you column is not Column A let me know and I'll adjust it to suit.

Hi Tuggy
It's been all work and no play for me lately! Not enough hours in a day either. I also got sick and tired of the problems EE was having and a list of ask and abondoned questions as long as my arm.

Hi Cri
I'll go take a quick look now!
