2     9

How do I wr

Answer 1

Even if a solution has been found. I think it is too complicated and oversized to use the pivot for this and it might not be possible in all scenarios. Here is one that can be found searching the internet for "max if excel" (e.g. see here; adapted)

{=MAX(IF(A:A=A1,B:B))}

Attention! This is an array formula, you have to enter it without the curly brackets and then press Ctrl+Shift+Enter to submit the formula.
