MATCH or VLOOKUP starting from the end of the range

Question

I have a table that looks like this

 A      B    
ID1  data 123
ID2  data 234
ID1  data 456
ID2  data 567

I am trying to find the best way to retrieve data 567 for ID2. Using MATCH (with option 0) or VLOOKUP (with option FALSE) on ID2 gives me access to the first record but I want to retrieve the last record.

I am using Excel 2010.

ps: I'd rather not use VBA or manipulate the data (sorting...).

Answer 1

With data in A1:B4 and D1="ID2", try entering in E1:

=LOOKUP(2,1/(A1:A4=D1),B1:B4)

Note: LOOKUP returns the last value if the lookup value is larger than any of the values in the lookup range. Any errors are ignored.

Answer 2

I know the question is already answered, but if any one is interested, here is the formula for a multiple criteria backwards lookup. =LOOKUP(2,1/(--(A1:A4=D1)*--(C1:C4=D2)),B1:B4)
