Sometimes a spreadsheet is more than you need. You may have a few receipts, a column of scores, or a list copied from notes. This site gives you a place to paste those numbers and immediately see the sum.
What the calculator does
It reads plain numbers separated by lines, spaces, commas, or semicolons, then shows the total, number of values, average, smallest value, and largest value. It supports positive and negative decimal numbers. If an entry contains text or a symbol it cannot read, it shows an error so you can correct the list.
How your numbers are handled
Regular calculation stays in your browser. If you choose the optional AI extraction feature, the text you enter is sent to Cloudflare Workers AI for parsing. We do not save your calculation history. See our Privacy Policy for more detail about site visits.
Our approach
We keep the main task front and center: enter numbers, check the count, and get the sum. The supporting statistics are there to help you catch a missing row or an unexpected value. For critical financial or professional decisions, check the source data and verify the result independently.
