Hello,

I made a stupid formula. It works but as my data increases it gets impossible. I need a better version of it. No VBA plz.

Code: 
=IF(H20=1,I20,IF(H20=2,IF(J20=1,I20&"--"&I21,K19),IF(H20=3,IF(J20=1,I20&"--"&I21&"--"&I22,K19),IF(H20=4,IF(J20=1,I20&"--"&I21&"--"&I22&"--"&I23,K19),IF(H20=5,IF(J20=1,I20&"--"&I21&"--"&I22&"--"&I23&"--"&I24,K19),IF(H20=6,IF(J20=1,I20&"--"&I21&"--"&I22&"--"&I23&"--"&I24&"--"&I25,K19),IF(H20=7,IF(J20=1,I20&"--"&I21&"--"&I22&"--"&I23&"--"&I24&"--"&I25&"--"&I26,K19),"Superieura7")
))))))

Basically the formula concatenates N amount of cells that are below each other.
The N amount to concatenate is on another cell in the same line.
You can have many groups of N.
The X amount helps you differenciate the groups as a new group always starts with 1...to N

In the example below, the tricky one is the group N=5 because there are 2 groups : The first one giving the result KLMNO and the second one PQRST

Excel Facts

When did Power Query debut in Excel?
Although it was an add-in in Excel 2010 & Excel 2013, Power Query became a part of Excel in 2016, in Data, Get & Transform Data.

What Excel version are you using?
I'm asking because in Excel 365 the function TEXTJOIN is available and a simple formula can be created. Otherwise, you need VBA.

Hi Marcello,

I am not using the 365 version.

I kind of guessed your conclusion and prepared that :
Function CONCATENATEMULTIPLE(Ref As Range, Separator As String) As String
Dim Cell As Range
Dim Result As String
For Each Cell In Ref
Result = Result & Cell.Value & Separator
Next Cell
CONCATENATEMULTIPLE = Left(Result, Len(Result) - 2)
End Function

Please note that I am using a double separator (--)

Now working on the magic VBA

Maybe...

Code: 
Function Conc(r As Range, sep As String)
    Dim rCell As Range, strAux As String
    
    For Each rCell In r.Offset(, 2).Resize(r.Value)
        strAux = strAux & " " & rCell.Value
    Next rCell
    Conc = Replace(Application.Trim(strAux), " ", sep)
End Function
