Excel formula for Beginners – How to find Unique values with multiple criteria in Excel

Generic formula

=UNIQUE(FILTER(data,(range1="b")*(range2>5)))

Summary

To extract a list of unique values from a set of data, while applying one or more logical criteria, you can use the UNIQUE function together with the FILTER function. In the example shown, the formula in D5 is:

=UNIQUE(FILTER(B5:B16,(C5:C16="b")*(D5:D16>5)))

which returns the 3 unique colors in group B with a quantity > 5.

Explanation

This example uses the UNIQUE function together with the FILTER function. The FILTER function removes data that does not meet required criteria, and the UNIQUE function further limits results to unique values only.

Working from the inside out, the FILTER function is used to collect source data in group B with a quantity greater than 5:

FILTER(B5:B16,(C5:C16="b")*(D5:D16>5)) // group is b, qty over 5

Insider filter, the expression used for the include argument:

 (C5:C16="b")*(D5:D16>5)

This is an example of using boolean logic to construct required logical criteria. The result is a boolean array like this:

{0;1;0;0;0;1;0;1;0;0;1;1}

This array is used to filter data, and the FILTER function returns another array as a result:

{"amber";"purple";"purple";"pink";"pink"}

This array is returned to the UNIQUE function as the array argument. UNIQUE then removes duplicates, and returns the final array:

{"amber";"purple";"pink"}

UNIQUE and FILTER are dynamic functions. If source data changes, output will update immediately.
