How do you I say while logic in excel formula.
OR maybe ue array formula to achieve it.

Please have al ook at the attached spreadsheet.

On tab key I have a key and ref.
in Ref column I am using  -> IF(ISNA(VLOOKUP(A2,rngRef,2,FALSE)),"",VLOOKUP(A2,rngRef,2,FALSE))  
To get ref_src from RANGE -> rngRef on tab KeySrc
basically just mapping the keys and getting the corresponding ref

Please let me know irf its not clear. I am sure you will figure out quikcly by looking at the attached sheet

Now What I am trying to acheive is that
there are two rows/records with same key '123'
and I am trying to get Ref  and combination of Ref_src for the same key
in the from Ref_src, Ref_src
so for key = 123
Ref would look like a,b

It would be very helpful if some one could help me out in achieving this

It's dificult to get the results in one cell with a formula (especially for more data which I asime you have) so how about the attached to get each Ref in a separate cell, i.e. in B2 paste this formula


confirmed with CTRL+SHIFT+ENTER nad copied across - when matches are exhausted you get blanks, e.g. in your example the Ref 3 formula in D2 displays a blank, see attached

I was wondering if it owuld be possible for you write the one that would work for
multiple records.

lKeyRow = 2
lSourceRow = 2

With Sheets("key")

'\loop through keys
sKey = .Cells(lKeyRow, 1)

'\loop through source for matches

sSource = Sheets("keysrc").Cells(lSourceRow, 1)
If sKey = sSource Then
sConcat = sConcat & Sheets("keysrc").Cells(lSourceRow, 2)
End If

lSourceRow = lSourceRow + 1
Loop While sSource <> ""

'\update key
.Cells(lKeyRow, 2) = sConcat

'\reset source vars
sConcat = ""
lSourceRow = 2

'\inc keyrow
lKeyRow = lKeyRow + 1

Loop While .Cells(lKeyRow, 1) <> ""

End With

Hello SameerMirza, the formula I suggested is easily extendable, e.g. changing all the A3 references to A50 we get this version


copied across as before and down if necessary, see attached revised version
