Excel/count & summing of unique values from a set of values


how to count unique values from a set of values where duplicates also exists

and how to sum the count of Unique values of another column, upon a given condition

any examples are welcome

Thanking you

warm Regards,

Nadeem -

The first part of your question is pretty straight forward. To do a count without duplicates you need to combine three formulas:

Which basically means, if you find a value within this range that is greater than 0 and is not a duplicate, then add 1 to the count. Copy and paste this formula into Excel and put numbers in the range, you'll see how it works.

For the second part of your question, I will need some idea of what your data looks like. I'm not sure if there are two columns or just one being used. I would prefer a quick example, such as:

Col A  Col B
1      a
2      b
3      c
