Return all "Vlookup" results

[brumby]

Hiya peeps.

I am trying to find a way to return all results from something similar to a Vlookup froma huge list and return all the results into a single cell, eg concatenated.

I have tried the LookupConcat UDF and is made the sheet go horribly slow, so looking for an alternative formula or with vba?

muchos!!!! xx

Here is a UDF from Krishnakumar of Excel Fox

Function MLOOKUP(ByRef TableArray As Range, ByVal LookupVal, ByRef LookupRange As Range, _
                                                        Optional ByVal NthMatch As Long)

If Not TypeOf TableArray Is Range Then
    MLOOKUP = CVErr(2042)
    Exit Function
End If
If Not TypeOf LookupRange Is Range Then
    MLOOKUP = CVErr(2042)
    Exit Function
End If
If TableArray.Rows.Count <> LookupRange.Rows.Count Then
    MLOOKUP = CVErr(2042)
    Exit Function
End If
If TableArray.Columns.Count <> LookupRange.Columns.Count Then
    MLOOKUP = CVErr(2042)
    Exit Function
End If


Dim LV_Cnt      As Long 'Count Loookup Value
Dim KA1, KA2
Dim r As Long, c As Long
Dim fFoundNo    As Long
Dim n           As Long
Dim strLval     As String


If IsNumeric(LookupVal) Then
    LV_Cnt = Evaluate("countif(" & LookupRange.Address & "," & LookupVal & ")")
    fFoundNo = Evaluate("match(" & CLng(LookupVal) & "," & LookupRange.Address & ",0)")
ElseIf IsDate(LookupVal) Then
    LV_Cnt = Evaluate("countif(" & LookupRange.Address & "," & CLng(LookupVal) & ")")
    fFoundNo = Evaluate("match(" & CLng(LookupVal) & "," & LookupRange.Address & ",0)")
Else
    strLval = """" & LookupVal & """"
    LV_Cnt = Evaluate("countif(" & LookupRange.Address & "," & strLval & ")")
    fFoundNo = Evaluate("match(" & strLval & "," & LookupRange.Address & ",0)")
End If


If NthMatch > 0 Then
    If LV_Cnt = 0 Or NthMatch > LV_Cnt Then
        MLOOKUP = CVErr(2042)
        Exit Function
    End If
End If




KA1 = TableArray: KA2 = LookupRange


For r = fFoundNo To UBound(KA1, 1)
    For c = 1 To UBound(KA1, 2)
        If LCase$(KA2(r, c)) = LCase$(LookupVal) Then
            If NthMatch Then
                n = n + 1
                If n = NthMatch Then
                    MLOOKUP = KA1(r, c)
                    Exit Function
                End If
            Else
                MLOOKUP = MLOOKUP & "," & KA1(r, c)
            End If
        End If
    Next
Next
MLOOKUP = Mid$(MLOOKUP, 2)
End Function
