Often you may want to find the max value of some dataset in Excel based on a category or group.

For example, suppose we have the following dataset and we’d like to find the max value of “points” for each team:

The following step-by-step example shows how to do so.

**Step 1: Enter the Data**

First, enter the data values into Excel:

**Step 2: Find the Unique Groups**

Next, we need to use the **=UNIQUE()** function to produce a list of unique team names.

In our example, we’ll type the following formula in cell **D2**:

=UNIQUE(A2:A16)

This will produce a list of unique teams:

**Step 3: Find the Max Value by Group**

Next, we will use the following formula to find the max points scored by each team:

=MAX(IF(A:A=D2,B:B))

We will type this formula into cell **E2** and then copy and paste it down to the remaining cells in column E:

This tells us:

- The max points scored by players on the Mavs is
**26**. - The max points scored by players on the Warriors is
**19**. - The max points scored by players on the Lakers is
**33**. - The max points scored by players on the Heat is
**19**. - The max points scored by players on the Celtics is
**29**.

**Note**: To calculate the minimum points scored by each team, simply replace the **MAX** in the formula with **MIN**.

The formula “=MAX(IF(A:A=D2,B:B))” only works like that when you enter it holding “Ctrl + Shift + Enter.” Otherwise it’s only giving you the MAX in B:B and that’s it. With this trick you tell excel it’s an arrayformula… works in google sheets, too.
