How to vlookup and return multiple values without duplicates in Excel? 

Sometimes, you may want to vlookup and return multiple matched values into a single cell at once. But, if there are some repeated values populated into the returned cells, how could you ignore the duplicates and only keep the unique values when returning all matching values as following screenshot shown in Excel?

doc return multiple unique values 1

Vlookup and return multiple matching values without duplicates by using User Defined Function


Vlookup and return multiple matching values without duplicates by using User Defined Function

The following VBA code can help you to return multiple matching values without duplicates, please do as this:

1. Hold down the Alt + F11 keys to open the Microsoft Visual Basic for Applications window.

2. Click Insert > Module, and paste the following code in the Module Window.

VBA code: Vlookup and return multiple unique matched values:

Function MultipleLookupNoRept(Lookupvalue As String, LookupRange As Range, ColumnNumber As Integer)
    Dim xDic As New Dictionary
    Dim xRows As Long
    Dim xStr As String
    Dim i As Long
    On Error Resume Next
    xRows = LookupRange.Rows.Count
    For i = 1 To xRows
        If LookupRange.Columns(1).Cells(i).Value = Lookupvalue Then
            xDic.Add LookupRange.Columns(ColumnNumber).Cells(i).Value, ""
        End If
    Next
    xStr = ""
    MultipleLookupNoRept = xStr
    If xDic.Count > 0 Then
        For i = 0 To xDic.Count - 1
            xStr = xStr & xDic.Keys(i) & ","
        Next
        MultipleLookupNoRept = Left(xStr, Len(xStr) - 1)
    End If
End Function

3. After inserting the code, then click Tools > References in the opened Microsoft Visual Basic for Applications window, and then, in the popped out References – VBAProject dialog box, check Microsoft Scripting Runtime option in the Available References list box, see screenshot:

doc return multiple unique values 2

4. Then click OK to close the dialog box, save and close the code window, return to the worksheet, and enter this formula: =MultipleLookupNoRept(E2,A2:C17,3) into a blank cell where you want to output the result, press Enter key to get the correct result as you need. See screenshot:

doc return multiple unique values 3

Note: In the above formula, E2 is the criteria that you want to vlookup, A2:C17 is the data range that you want to use, the number 3 is the column number which contains the returned values.

    Hi

    I wanted to create a list in a table from this instead of all results in one cell. So I have used a formula similar below (what you have suggested)

    =LOOKUP(2, 1/((COUNTIF($E$1:E1, $B$2:$B$12)=0)*($D$2=$A$2:$A$12)), $B$2:$B$12)

    However, this is taking a long time to process from a large set of data.
    Is there any alternative method to process this faster?
    Thanks again

    xStr = xStr & xDic.Keys(I) & "," to be this: xStr = xStr & xDic.Keys(I) & ", "

    Is there a way to replace "," with in-cell ALT+ENTER, so that the results will be in the same cell but on different lines? Do I need to introduce additional VBA module for that and combine them?

    Also, this code is quite slow when looping over huge tables. Anyone knows any faster solutions?

      Hi, Imre,
      To separate the result values by Alt + Enter keys, please apply the following User Defined Function:

      Function MultipleLookupNoRept(Lookupvalue As String, LookupRange As Range, ColumnNumber As Integer)
      Dim xDic As New Dictionary
      Dim xRows As Long
      Dim xStr As String
      Dim i As Long
      On Error Resume Next
      xRows = LookupRange.Rows.Count
      For i = 1 To xRows
      If LookupRange.Columns(1).Cells(i).Value = Lookupvalue Then
      xDic.Add LookupRange.Columns(ColumnNumber).Cells(i).Value, ""
      End If
      Next
      xStr = ""
      MultipleLookupNoRept = xStr
      If xDic.Count > 0 Then
      For i = 0 To xDic.Count - 1
      xStr = xStr & xDic.Keys(i) & Chr(10) + Chr(13)
      Next
      MultipleLookupNoRept = Left(xStr, Len(xStr) - 1)
      End If
      Debug.Print xStr
      End Function

      And then do with the above steps in this article, at last, after entering the formula, you should click Wrap Text under the Home tab.

    Is there a way to add a space in between the multiple values retrieved in the results without introducing a comma at the end of the list? For example your result above would show as: "Emily, James, Daisy, Gary" instead of like this: "Emily,James,Daisy,Gary"

    I tried to edit this portion of the VBA code: xStr = xStr & xDic.Keys(I) & "," to be this: xStr = xStr & xDic.Keys(I) & ", "

    That did add the space in between the values, but it also added a comma after the last value. "Emily, James, Daisy, Gary,"

    Is there a way to make it work with the space but without the extra comma after the last value?

      Hello, Demetre,
      Use the space to separate the values, you just need to change the vba code:
      from xStr = xStr & xDic.Keys(i) & "," to be this: xStr = xStr & xDic.Keys(i) & " "

      Please try it.

      Hello, Tom,
      If you want to extract the unique values in a list of cells instead of one cell, the following formula may help you:

      =LOOKUP(2, 1/((COUNTIF($E$1:E1, $B$2:$B$12)=0)*($D$2=$A$2:$A$12)), $B$2:$B$12)

      Please try it.

        Hi Skyyang,

        Thank you very much for this formula.
        This works for me. However, it is taking a long time to process from a large set of data.
        Can we modify this formula to work this bit faster?
        Thanks again
