'The above statement will hide all duplicate rows in the given range

'Now we have remove the the hidden rows and leave the visible rows (unique rows)
Set myDuplicateRange = Nothing
For Each Row In myRng.Rows
        If Row.EntireRow.Hidden Then
            If myDuplicateRange Is Nothing Then
                Set myDuplicateRange = Row
            Else
                Set myDuplicateRange = Union(myDuplicateRange, Row)
            End If
        End If
    Next

    If Not myDuplicateRange Is Nothing Then myDuplicateRange.EntireRow.Delete

'Now clear the advanced filters and show all records
    ActiveSheet.ShowAllData

'In other way, You can copy all visible rows (Unique rows) into the another sheet, Instead of removing the duplicates
End Sub

    Hi
    If I have ‘n’ number of duplicate for a record and i want to keep only the last record (last record will be always at the end as per my source data file). My first identifier should be the Column B and second identifier is Column F. And to be precise I want to remove the duplicate values where both B and F matches. If B and F do not match then its not duplicate row.
    Appreciate if you can help me.

    Regards
    Arafin

        'Now Find Last Row - Assuming you will have maximum of 100000
        If Cells(100000, Col1).End(xlUp).Row > Cells(100000, Col2).End(xlUp).Row Then
            lastRow = Cells(100000, Col1).End(xlUp).Row

    Hi hope you can help me with this too. I read forums already but did not seem to find an answer specific to my need.I have set of data in sheet1, and I need to identify duplicate values using column name”part” only. Then, I need to transfer the duplicates to sheet2 (retain only 1 unique value in sheet1). The criteria of which of the duplicates will be transferred to sheet2, is column “count”. duplicate values in column “part” must be 0 in column “count”, for the row to be transferred to sheet2. by the way, header is in row1, and the goal is to transfer duplicate “part” but 0 in “count” to sheet2. Thanks a lot.
