Question

I would like to get e.g. min or max value from column2 for same value in column1.
In mine example I want max value from column2 for value A (column1) and that is 18, and for B is 27.

I’ve tried with array function but I cannot manage it to work properly.

Tnx for any tip or solution.

Example:

Column1 Column2 Max_value

A       1       18
A       5       18
A       18      18
A       3       18
A       4       18
B       2       27
B       5       27
B       18      27
B       27      27
B       5       27
B       3       27

Sorry for poor example, but I couldn’t post picture, my rank is not high enough 🙂

Answer 1

The standard “array formula” is like this for C2

=MAX(IF(A$2:A$100=A2,B$2:B$100))

confirmed with CTRL+SHIFT+ENTER and copied down column – adjust ranges as required

replace MAX with MIN to get the minimum values in the next column
