Hello,

I have two strings of letters (columns String A and String B) and I want to transform them into strings like the ones in Solution 1 and Solution 2 correspondingly.

String AString BSolution ASolution B
7-6-1-3-4-2-2DDDDDTT
7-6-1-3-4-2
DDDDDT
3-3-0-2-0-0
DDTDTT
3-0-2-0DTDT
6-8-8-13-13-11-10-14-14-7-4-7-2-1-0-3-9DDDDDDDDDDDDDDDDT6-8-13-11-10-14-7-4-7-2-1-0-3-9
DDDDDDDDDDDDDT

In the case of String A, I need to remove any adjacent duplicate numbers (the numbers are separated by a "-"), so the string 6-8-8-13-13-11-10-14-14-7-4-7-2-1-0-3-9 would turn into 6-8-13-11-10-14-7-4-7-2-1-0-3-9.
String B is a little bit more complicated: both String A and String B have the same amount of items, and I want to transform String 2 depending on the transformation of String 1 into Solution 1. For example, in my data, I have 6-8-8-13-13-11-10-14-14-7-4-7-2-1-0-3-9 as String 1 and DDDDDDDDDDDDDDDDT as String 2. Solution 1 would be 6-8-13-11-10-14-7-4-7-2-1-0-3-9 (remove adjacent duplicate numbers) and Solution 2 would be DDDDDDDDDDDDDT (remove characters that are in the same position as the numbers removed from String 1).

I hope this makes sense and I'm happy to provide any further clarification.

Best,

See what happens with this one.

Sorry for the late reply.

I'm still getting the same error message.

Excel Facts

Links? Where??
If Excel says you have links but you can't find them, go to Formulas, Name Manager. Look for old links to dead workbooks & delete.
VBA Code:
Sub test()

    For i = 2 To Cells(Rows.Count, 1).End(3).Row
   
        bol = Split(Cells(i, 1).Value, "-")
        yeni = Mid(Cells(i, 2).Value, 1, 1)
        For ii = 1 To UBound(bol)
            If bol(ii - 1) = bol(ii) Then
                ekle = ""
                bol(ii) = ""
            Else
                ekle = Mid(Cells(i, 2).Value, ii + 1, 1)
            End If
            yeni = yeni & ekle
        Next ii
        Cells(i, 5).Value = Replace(WorksheetFunction.Trim(Join(bol, " ")), " ", "-")
        Cells(i, 6).Value = yeni
   
    Next i
End Sub
Thanks for the reply. Your code works but it only collapses double characters (9-9 to 9) but it does not work for triple characters (9-9-9 to 9-9)

Could you be using a regional Excel version that uses ; instead of , as the function argument separator?

What happens if you try each of these for the Solution A question?
Excel Formula:
=LET(ts;TEXTSPLIT(A2;"-");s;SEQUENCE(COLUMNS(ts)-1);TEXTJOIN("-";1;INDEX(ts;1);IF(INDEX(ts;s+1)=INDEX(ts;s);"";INDEX(ts;s+1))))
Excel Formula:
=LET(n;LEN(A2)-LEN(SUBSTITUTE(A2;"-";""));s;SEQUENCE(n);ss;SEQUENCE(n+1);ts;TRIM(MID(SUBSTITUTE(A2;"-";REPT(" ";100));ss*100-99;100));TEXTJOIN("-";1;INDEX(ts;1);IF(INDEX(ts;s+1)=INDEX(ts;s);"";INDEX(ts;s+1))))

Hi Pete, I think this is not the case - as @Fluff previous code here: Remove adjacent duplicate characters from String A and remove characters in the same position from String B. worked just find for him.
Yes, I had seen some of the OP's previous threads where that did not seem to be the issue. However, so far, the only way that I have been able to reproduce the particular error reported by the OP is to change commas to semicolons in my version so though the question was worth asking.

Hi, thanks for your reply.

The first solution gives me a #NAME? error.
The second solution seems to work perfectly fine :)

I didn't miss the post right before veyselemre's VBA, I also tried it and got the "The first argument of LET must be a valid name" message.

Great news! So you should be able to use both the suggestions from post #9 if you swap all the commas for semicolons.

.. and you need to remember that swap for any future suggestions in the forum - that mostly will use commas.

... would be interested to know if Fluffs previous code is still working for you (on those items that do not have the "-" between them though ?

Thanks! I've already marked the post as the solution ;)
