How to use IndexMatch formula that ignores duplicates
Requirement:
To find a way around getting duplicates when running an IndexMatch formula. For example, it looks at column O (O10, for example and then searches through range D2:D115 to return whatever is in the adjacent column A once it finds it.
At the moment, there are some duplicate numbers in column O and so it's always returning the same result. Is there a way of having an extra bit in there somewhere to say "I've already found , so ignore that and find the next result"?
Solution:
Use this Array* formula:
=INDEX($A$2:$A$115,SMALL(IF($D$2:$D$115=O10,ROW($A$2:$A$115)-ROW($A$2)+1),ROWS(O$10:O10)))
