Saved from a previous post:
If you want exact matches for just two columns (and return a value from a
third), you could use:
=index(othersheet!$c$1:$c$100,
match(1,(a2=othersheet!$a$1:$a$100)
*(b2=othersheet!$b$1:$b$100),0))
(all in one cell)
This is an array formula. Hit ctrl-shift-enter instead of enter. If you do it
correctly, excel will wrap curly brackets {} around your formula. (don't type
them yourself.)
Adjust the range to match--but you can only use the whole column in xl2007.
This returns the value in othersheet column C when column A and B (of
othersheet) match A2 and B2 of the sheet with the formula.
And you can add more conditions by just adding more stuff to that product
portion of the formula:
=index(othersheet!$d$1:$d$100,
match(1,(a2=othersheet!$a$1:$a$100)
*(b2=othersheet!$b$1:$b$100)
*(c2=othersheet!$c$1:$c$100),0))
