Count the number of unique values in a range [Quick Tip]
Excel Formula to Count Number of Unique Values
Assuming we have a list of values in the range:B5:B15 and we want to know how many unique values are there,
you can write the oh so wonderful sumproduct formula like this:
How this formula works?
COUNTIF(B5:B15,B5:B15) of the formula returns the individual item counts. So in our example range, the values would be:
5,1,2,5,1,1,1,2,5,5,5. When you add up the reciprocals of these values, you will get the count of unique values in the range.
I am leaving that to your imagination.
