The bigger your spreadsheet, the more you need INDEX and MATCH functions, which you can combine with SUM, AVERAGE, and MAX to refine your searches.

There's one trick, though, that separates the quants from the interns. That trick is Index/Match, a function that can find any value in any spreadsheet.

You probably use VLOOKUP() function to find exact matches in Microsoft Excel, but you can also find the closest value when you don't know the exact value.
