Deleting Duplicate Text Values

Everybody runs into the need at one time or another—to delete duplicate entries from a list of text entries. Suppose you have the text values in column A of a worksheet, and they run for about 500 rows. If you want to delete any duplicates in the list, you may be looking for the easiest way to do it. There are actually multiple ways you can accomplish this task in Excel.

Using the Delete Duplicates Tool

Perhaps the simplest method is to select the data from which you want to delete duplicates and then display the Data tab of the ribbon. Click the Remove Duplicates tool, in the Data Tools group. Excel displays the Remove Duplicates dialog box.

The great thing about the Remove Duplicates dialog box is that it lists the names of each column in your data. (The tool assumes that you have heading labels in the first row of your data.) You can then make sure there is a check mark next to each column you want checked for duplicates. When you click the OK button, your data in analyzed and the duplicate rows removed. (Again, duplicates are determined based on the columns selected in the Remove Duplicates dialog box.)

Using Data Filtering

Another manual method is to use data filtering to determine the unique values. Make sure the column has a label at the top of it, then select a cell in the column. Display the Data tab of the ribbon and click Advanced in the Sort & Filter group. Use the controls in the resulting dialog box to specify that you want to copy the unique values to another location which you specify.

Using a Formula

You can also use a formula to manually determine the duplicates in the list. Sort the values in the column, and then enter the following formula in cell B2:


Copy the formula down to all the cells in column B that have a corresponding value in column A. Select all the values in column B and press Ctrl+C. Use Paste Special to paste just the values into the same selected cells. You've now converted the formulas into their results. Sort the two columns according to the contents of column B, and all of your duplicate rows will be in one area. Delete these rows, and you have your finished list of unique values.

Using a Macro

The manual approaches are fast and easy, but if you routinely have to delete duplicate values from a column, a macro may be more your style. The following macro relies on data filtering, much like the earlier manual method:

Sub CreateUniqueList()
    Dim rData As Range
    Dim rTemp As Range

    Set rData = Range(Range("a1"), Range("A1048576").End(xlUp))
    Set rTemp = rData.Offset(0, -1)
    rData.AdvancedFilter _
        Action:=xlFilterCopy, _
        CopyToRange:=rTemp, _

    rTemp.EntireColumn.Copy _
    Application.CutCopyMode = False
    Set rData = Nothing
    Set rTemp = Nothing
End Sub

The macro creates a temporary column, uses advanced filtering to copy the unique values to that column, then deletes the original data column. The result is just unique values in column A. If you don't want your macro to use the data filtering feature of Excel, then the following much shorter macro will do the trick:

Sub RemoveDups()
    Dim rData As Range

    Set rData = Range(Range("a1"), Range("A1048576").End(xlUp))
    rData.RemoveDuplicates Columns:=Array(1), Header:=xlYes
End Sub

The key in this macro is using the RemoveDuplicates method, which relies on an array that contains the column numbers you want to check for duplicates. The macro shown here operates only on the contents of column A, but you could easily modify it to work on data in more than a single column. All you would need to do is to change rData so that it represented the larger data area and then modify the columns parameter so that it pointed to the columns you want checked:

    rData.RemoveDuplicates Columns:=Array(1,4), Header:=xlYes

Another macro-based approach is to develop your own code to check the values in the data set, in this manner:

Sub DelDups()
    Dim rngSrc As Range
    Dim NumRows As Integer
    Dim ThisRow As Integer
    Dim ThatRow As Integer
    Dim ThisCol As Integer
    Dim J As Integer, K As Integer

    Application.ScreenUpdating = False
    Set rngSrc = ActiveSheet.Range(ActiveWindow.Selection.Address)

    NumRows = rngSrc.Rows.Count
    ThisRow = rngSrc.Row
    ThatRow = ThisRow + NumRows - 1
    ThisCol = rngSrc.Column

    'Start wiping out duplicates
    For J = ThisRow To (ThatRow - 1)
        If Cells(J, ThisCol) > "" Then
            For K = (J + 1) To ThatRow
                If Cells(J, ThisCol) = Cells(K, ThisCol) Then
                    Cells(K, ThisCol) = ""
                End If
            Next K
        End If
    Next J

    'Remove cells that are empty
    For J = ThatRow To ThisRow Step -1
        If Cells(J, ThisCol) = "" Then
            Cells(J, ThisCol).Delete xlShiftUp
        End If
    Next J
    Application.ScreenUpdating = True
End Sub

The macro works on a selection you make before calling it. Thus, if you need to remove duplicate cells from the range A2:A974, simply select that range and then run the macro. When the macro is complete, the duplicate cells are removed, as are any blank cells.

You can write a formula to identify duplicates in a non-sorted list easily too.


(in R1C1) =IF(COUNTIF(R1C1:RC1,RC1)=1,RC1,"")

This counts how many entries in column A so far (i.e. starting in row 1 and going down) match the current value. If there is only 1 such case, it means the current value is the first instance in the column, and is returned.

The "Remove Duplicates" tool is a great tool for removing duplicates in a long list of email contacts.

You can make the "much shorter macro" even shorter like this one-liner:

Sub RemoveDups()
Range("A:A").RemoveDuplicates Header:=xlYes, Columns:=Array(1)
End Sub

There is no need to search for the last used cell in column A since Excel will ignore the remaining blank cells in the column. You can make it even a little bit shorter by using the shortcut version [A:A] instead of Range("A:A").
