Summary

Sum a List of Numbers sums the set of numbers separated by commas, spaces, or new lines. The tool also typically displays the amount of data, the mean, the minimum, and the maximum values. When processing input, ignore empty entries and validate numbers so that the result is not NaN.

Key points

Common divisors: commas, spaces, semicolons, and new lines
Convert each entry to a number before adding it up
Ignore the empty string so it doesn't count as zero.
Average = the sum divided by the number of valid data
Be careful with decimal dividers of commas versus thousands
