Numbers get scattered through text: prices in a receipt, scores in a match report, quantities in an order email, readings in a log. Often you want the numbers by themselves, or their total. Copying and typing each into a calculator is where mistakes come from.
Paste the text and every number appears as a list. Above it, you get a count, the sum, the average, the smallest and the largest.
What it recognises
Whole numbers like 42. Decimals like 4.50. Negatives with a leading minus sign, like -3.5. Numbers with commas as thousands separators, like 1,200, which are read as 1200 in the totals while still being shown the way you wrote them.
So “Sold 12 units at $4.50, then 1,200 more” gives you 12, 4.50 and 1,200, with a sum of 1216.5.
Things that trip it up
Because the tool looks at characters and not at meaning, a few patterns give surprising results. These are worth checking before you trust a total:
Hyphens read as minus signs. A phone number like 555-0100 is read as 555 and -0100, and a date like 2026-10-21 is read as 2026, -10 and -21. Take out dates and phone numbers before summing, or use filter lines to remove the lines that contain them.
Commas in a list. 1,2,3 is read as the single number 123, since a comma between digits looks like a thousands separator. Put spaces after commas in a list (“1, 2, 3”) and each number is read separately.
Numbers inside words. Room 12B yields 12, and a code like abc123 yields 123. That is usually fine, sometimes not.
Currency. Dollar and pound signs are not included, and neither are units. $4.50 is extracted as 4.50.
Settings
“Remove repeats” lists each number once, but the sum, average and range always use every number found, repeats included, so the total is true to your text. “Sort” orders by value, not alphabetically, which makes the range easy to see. Output can be one per line or a comma-separated line, which pastes straight into a spreadsheet.
Companion tools
For the opposite job, deleting numbers and keeping the words, use remove numbers. To write a number out in words for a cheque or contract, there is the number to words converter, and for Roman numerals, the Roman numeral converter. If your list of numbers needs ordering by line, sort lines has a numeric mode.
