Excel does not offer a “max if” function, so to get a maximum value based on criteria, you can use the MAX function together with the IF function.
This is an array formula and must be entered with Control + Shift + Enter.
In the example shown, the formula in cell G6 is:
Where names is the named range B6:B17, and times is the named range D6:D17.
How this formula works
The IF function is evaluated first. The logical test names=F6 returns an array of TRUE / FALSE values, where TRUE values correspond to rows where the name matches “Hannah” in F6. The “value if true” for IF is the named range “times”, which returns the full set of times. No “value if false” is provided, so the result of IF is an array that contains a time (where the logical test returned TRUE) and FALSE where it didn’t.
The MAX function then returns the maximum value in this array. FALSE values are automatically ignored.
