If you have a list of text string, now, you need to remove the duplicate characters as following screenshot shown. Here, I can talk about a VBA code to deal with it.

doc-remove-duplicate-characters-1

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: Remove duplicate characters of text string in a cell

Function RemoveDupes1(pWorkRng As Range) As String
'Updateby Extendoffice
Dim xValue As String
Dim xChar As String
Dim xOutValue As String
Set xDic = CreateObject("Scripting.Dictionary")
xValue = pWorkRng.Value
For i = 1 To VBA.Len(xValue)
    xChar = VBA.Mid(xValue, i, 1)
    If xDic.Exists(xChar) Then
    Else
        xDic(xChar) = ""
        xOutValue = xOutValue & xChar
    End If
Next
RemoveDupes1 = xOutValue
End Function

3. Then save and close this code, go back to the worksheet, and enter this formula =removedupes1(A2) (A2 is the data cell you want to remove duplicates from) into a blank cell besides your data, see screenshot:

doc-remove-duplicate-characters-1

4. And then drag the fill handle over to the range cells that you want to apply this formula, all the duplicate characters have been removed from each cell immediately.

If there are some words which are separated by certain punctuation marks in a cell, you can also remove the duplicate words as you like. Please do with the following steps:

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: Remove duplicate words separated by punctuation of a cell

Function RemoveDupes2(txt As String, Optional delim As String = " ") As String
    Dim x
    'Updateby Extendoffice
    With CreateObject("Scripting.Dictionary")
        .CompareMode = vbTextCompare
        For Each x In Split(txt, delim)
            If Trim(x) <> "" And Not .exists(Trim(x)) Then .Add Trim(x), Nothing
        Next
        If .Count > 0 Then RemoveDupes2 = Join(.keys, delim)
    End With
End Function

3. Then save and close this code, return to the worksheet, and enter this formula =RemoveDupes2(A2,",") into a blank cell next to your data, see screenshot:

doc-remove-duplicate-characters-1

4. Then copy down the formula to your needed cells, and all the duplicate words have been removed from every cells. See screenshot:

doc-remove-duplicate-characters-1

Note: In the above formula, A2 indicates the cell that you want to use, and the comma (,) stands for the punctuation mark which separates the words in a cell, you can change it to any other punctuations to your need.

Not sure if this thread is still alive. I am trying to use this for something as simple as what is shown in the chart above and I keep on receiving #NAME? error. Cell A2 has XXX, YYY, XXX, AAA I can't quite understand what I am doing wrong. I have the code in my personal workbook. Would that be the issue?
