Returning the column header of max value on per row basis

Question

I have a spreadsheet whereby on a monthly basis I need to return the top product based on a table for that month. I have copied a screenshot of my current setup below.

I am currently doing this by creating an additional column (column H) which uses the INDEX, MATCH and MAX functions to return the name of the highest product in that row.

I then use another INDEX MATCH as a lookup in cells K4 and L4 to return the value for that month.

The problem is that my table expands each month as a new row is added and I wanted to find out if there was a way to combine both the formulas into one. So that all I would need to do is update the current and previous months in cells K3 and L3. I have the same setup across quite a few sheets so want to automate as much as possible.

Would love some help, ideally without using VBA if possible at all.

Answer 1

You could use this formula in K4 and drag it across to L4:

=INDEX($B1:$H1,1,MATCH(MAX(INDEX($B:$H,MATCH(K2,$A:$A,0),0)),INDEX($B:$H,MATCH(K2,$A:$A,0),0),0))
