Excel formula to find Max and return a column from the matching row

Question

My data looks some thing like this:

Product 1	Date	Site1_Sales	Site2_Sales	Site2_Sales
x1	1-Jan	100	200	300
x2	2-Jan	60	51	150
X1	2- Jan	110	30	40

There will be 1000s of rows with repeated Product but with unique dates. This is what I would like to find:

1. What was the Max sales for a product? and on which date? I tried using Maxifs but it ends up with value error it looks it can handle only continuous ranges.
2. What was the sum of sales for a product for specific period eg first 10 days?

Any help is really appreciated. Thank you

Answer 1

1. see “Remarks” about #value error:

2. SUMIF works in the same way as MAXIF (eg you could use a start date and end date as multiple criteria)

3. FILTER should help you to find the date(s) of max. Sales as well
