Google Sheets: how to find max value in column B, corresponding values in column A, and max among these
Suppose you have data in the columns A, B from row 2 to 4. Put MAX(B2:B4) somewhere (in this example, I put it in B6). Then for the corresponding max in A you can use the formula MAX(ARRAYFORMULA(IF(B2:B4 = $B$6,A2:A4))).
