What the tool does, how to run it, and what to expect from the result.
Paste numbers separated by commas, spaces or new lines, including a column copied from a spreadsheet, and the sum updates as you type. 19.99, 4.50, 12.00 and 7.25 add up to 43.74. Anything that is not a number is skipped and listed, so a stray label does not break the total.
A quick way to understand who this helps, what it solves, and where it connects next.
Students, teachers, analysts and researchers working with data.

Short answers for the questions people usually have before trying a utility like this.
Yes. Each cell arrives on its own line, which the calculator reads as separate numbers.
No: a comma separates numbers, so write 1200 rather than 1,200.
