Whats good or unique about it
Excel"s SUMIF function is more extensive than SumCat. SumCat has the restriction that a Category has to be a number, and a blank will be interpreted as zero. If you prefer your categories as numbers, you prefer the more rigid style of this function.
You do not have to specify a value for the minimum or maximum category numbers. There are two category selection methods here: one being the chosen categories and the other being the minimum and maximum category numbers. If a category meeets either of these two criteria, then it is selected.
