If i wanted to return more than one column (the join range), eg to concatenate a few columns, would this be possible with a simple variation?

OK, the attached file has the following formula:

Function lookupjoin(SearchValue As Variant, SearchRange As Range, JoinRange As Range, wordSeperator As String, Optional LineSeperator As String)

Dim x As Long, y As Long, z As Long
Dim d As Object
Set d = CreateObject("Scripting.Dictionary")
Dim colArr
Dim JoinString As String

z = JoinRange.Columns.Count
ReDim colArr(1 To z)

For x = 1 To SearchRange.Count
    If SearchRange(x, 1) = SearchValue Then
       For y = 1 To z
            colArr(y) = JoinRange(x, y)
       Next y
       JoinString = Join(colArr, wordSeperator)
       If Not d.exists(JoinString) Then
            d.Add JoinString, ""
       End If
    
    End If
Next x

If LineSeperator = Empty Then LineSeperator = vbCrLf
lookupjoin = Join(d.keys, LineSeperator)

End Function

Open in new window


This will allow for a Range to be concatenated.
It does have the optional second line joiner (set to default to crlf).
It should be quite apparent how it works from the examples in the workbook.
Any questions let me know.

Works great thanks! Simple question (i hope) how can I enter a discontiguous JoinRange, eg if i want to return columns B and D for example.

Cheers

That is not as simple as you would hope, you could add a variable for columns to include/exclude.
But passing a group of ranges is not so easy as they get separated by commas which ruins the formula.
How many columns need to be joined? Do they change?

Maybe 3 or 4 columns. They probably won't change. Solution needs to be fairly user-friendly as I won't be doing the updates to rows etc, and user will just copy-paste formulae down etc.

OK the attached has a change to allow for selecting the columns as a set of numbers...

so for columns 1 and 3 you would enter 13.
for columns 1 and 2 and 3 use 123.

Have a look and see if it is better.

Have hard coded the spaces and line feeds as this may be better in the code.
