- Optionally ignore zeros, then copy the sum or the cleaned list of numbers.
How to Use the Add Numbers Tool
- Paste or type your numbers into the input box. Separate values with spaces, commas, tabs, or new lines — or choose Auto to detect separators.

- Copy the sum, or copy the cleaned number list with your preferred separator and decimal mark for spreadsheets and reports.
Why Use the Add Numbers Tool?
This free online add numbers tool is built for anyone who needs to calculate the sum of a list of numbers quickly — from expense receipts and research datasets to columns copied from Excel or Google Sheets. Paste mixed text and the tool keeps only recognized numbers so you get an accurate total without cleaning the data by hand.
Everything runs in your browser. Your numbers are never uploaded or stored on a server. Pair it with the random number generator when you need sample values, or the unit converter when you need to normalize units before summing.
Frequently Asked Questions (FAQ)
How do I add numbers using this tool?
Paste or type your numbers in the input field. Separate them with spaces, commas, tabs, or line breaks, then click "Add Numbers" to get the total sum and count of valid values.
What separators can I use?
You can use spaces, commas, tabs, or new lines. If you are unsure, select "Auto" and the tool will detect separators for you.
Can I paste a column from Excel or Google Sheets?
Yes. Copy a column of numbers from a spreadsheet and paste it here. New-line separated values work out of the box, and Auto mode handles most pasted lists.
Can I choose a different decimal mark?
Yes. Switch between dot (.) and comma (,) as the decimal mark so international formats like 1,5 and 1.5 are parsed correctly.
Can I ignore zeros in my calculation?
Yes. Check "Ignore Zero" to exclude zero values and only sum the remaining numbers.
Is my number data private?
Yes. Summation runs entirely in your browser. ToolGenie does not upload, store, or share the numbers you paste on this page.
Tips for Using the Add Numbers Tool
- Tip 1: Use the "Auto" separator when pasting mixed lists so the tool detects spaces, commas, and line breaks for you.
- Tip 2: Match the decimal mark to your locale — comma for many European formats, dot for US-style numbers.
- Tip 3: Enable Ignore Zero when empty or placeholder zeros should not affect the total.
- Tip 4: Customize the copy separator and decimal mark before pasting results into another app or spreadsheet.
