I have way too much data. Is there a way to reduce how much data I have by
running a filter or smoothing algorith. there are many versions out there and
i'd think there would be a function in excel. I have too many (more than
32,000) data points and would like to reduce by 1/2 or 1/4 the data. I have
way too many points and can sacrafise quite a lot.
