What is an equivalent for INDEX in ARRAYFORMULA?

Question

I have (what I thought was) a simple lookup table holding some exchange rates. There I am looking up values based on row and column indices.

How can I do that in an ARRA

Answer 1

you can replace index by Vlookup by writing "Anything" in x!C1 and use : =ARRAYFORMULA(Vlookup("Anything", TRANSPOSE(x!C2:C),F1:F))
