Hi All, I intend to use this piece of UDF I found on internet for my requirement -
Function MYVLOOKUP(lookupval, lookuprange As Range, indexcol As Long) Dim r As Range Dim result As String result = "" For Each r In lookuprange If r = lookupval Then result = result & " " & r.Offset(0, indexcol - 1) End If Next r MYVLOOKUP = result End Function Formula *=MYVLOOKUP(lookup_value,lookup_range,return_column_no.)* It does join all the matches of the lookup in one cell (results separated by a space) and this fulfils my purpose. The problem is, it is terribly slow. I couldn't manage to get results for a 50000 rows data with around 11000 lookup values despite waiting of 2-3 hours and eventually had to raise hands in despair. Any ideas to (considerably) speed it up?? PS: My data is in Table format and changing its format doesn't change much. I can provide a sample file, if need be. Many thanks in advance.
