About this tool
The two numbers every list has
Paste your numbers and the tool returns the minimum and maximum — the boundaries of your data. Everything else you might ask about a list (range, outliers, sanity) starts from these two values.
Min and max as a data sanity check
Before trusting any average, check the extremes: a minimum of zero or negative in a dataset of prices means dirty data, and a maximum ten times the next value means an outlier or a typo. Two numbers, read in seconds, catching most import errors.
From min and max to the full picture
The range is max minus min; the average adds the center; sorting with the number sorter shows the distribution. Together they are the whole first-pass analysis of any number list.
Frequently asked questions
What happens with an empty list?
No numbers, no min or max — the tool reports that no values were found rather than inventing a zero.
How do negatives and decimals factor in?
Fully — numeric comparison covers negatives, decimals, and mixtures, and the extreme values are true numeric extremes.
Does a single-number list just return that number twice?
Yes — with one value, it is both the minimum and the maximum, which is mathematically honest.
