I am trying to compare two different Excel (2010/xlsx) tables with related data to find matches. They would be on different sheets but in the same workbook (not that it should affect the problem).
I think the best route is some combination of sumproduct
, match
, and index
... but I haven't been able to get them to work so far. I see the main question (cell G17) being solved by creating a subset of rows from Table 2 to compare against their corresponding data in Table 1 (index/match), then using arrays to do a multiple criteria selection to count how many match the criteria I chose (sumproduct
).
I have played around with vlookup
, countif(s)
, and sumif(s)
but haven't seen a good way to apply them to this problem.
You can use SUMIF as a "quasi-lookup" like this
=SUMPRODUCT((file="doc")*(modified < SUMIF(user,creator,create)))
