What is Free Online Number Sum & Stats Tool?

Number Sum is a fast utility for totaling lists of numeric values. Instead of manually entering numbers into a standard calculator one by one, you can paste an entire column from a spreadsheet, a list from a document, or values from an invoice. The tool automatically extracts the numbers and provides the sum along with other helpful statistics like the average and range.

How it works

The tool uses a regular expression to split the input by common delimiters (newline, comma, semicolon). It filters out non-numeric strings and converts the rest into JavaScript numbers, then uses standard array reducers to calculate the statistics.

Features & Benefits

Instantly totals long lists of numbers
Provides count, average, minimum, and maximum values
Handles messy input (ignores non-numeric text automatically)
Runs locally — perfect for private financial data

Frequently Asked Questions

Can it handle currency symbols?

It ignores common symbols like '$' if they are next to the number, but for best results, use plain numeric values.

What delimiters are supported?

Newlines, commas, and semicolons are all used to separate numbers.
