Number Sorter
Paste a list of numbers and sort it instantly in ascending or descending order, with optional duplicate removal — free and private, right in your browser.
How to use the Number Sorter
- Paste your list. Drop your numbers into the box above — separated by commas, spaces, semicolons or line breaks. Decimals, negatives and E notation (1e3) all work.
- Choose the order. Pick ascending (smallest first) or descending (largest first), select an output separator, and tick Remove duplicates if you only want each value once.
- Copy or download. The list is re-sorted instantly as you type. Grab the result with the copy button or save it as a .txt file.
About this tool
This free number sorter arranges any list of numbers in true numeric order — so 9 comes before 10 and -5 before 2, unlike an alphabetical sort where "10" would sort before "9". It is handy for organizing survey results, exam scores, measurement series, lottery picks, invoice amounts or any data column before pasting it into a spreadsheet or report. Alongside the sorted list you instantly get the count, number of unique values, minimum, maximum, sum and average.
The sorter keeps your numbers exactly as you typed them (1.50 stays 1.50) and only changes their order, and the optional duplicate filter keeps the first occurrence of each value. Everything runs locally in your browser — your data is never uploaded or stored, so it is safe to sort confidential figures like salaries or account totals.
Frequently asked questions
Which separators can I use between numbers?
Commas, semicolons, spaces, tabs and new lines all work, in any mix. Note that commas are treated as separators, so type thousands without commas: 1234 rather than 1,234 (which would be read as 1 and 234).
What happens to entries that are not numbers?
Non-numeric entries such as words or malformed values are skipped, and the tool shows you exactly which entries were ignored so nothing disappears silently. Valid formats include integers, decimals, negatives and scientific notation like 2.5e6.
How does duplicate removal decide what is a duplicate?
Values are compared numerically, so 7, 7.0 and 007 count as the same number and only the first one you entered is kept. Untick the option to keep every occurrence.
Is there a limit on how many numbers I can sort?
No fixed limit — the sort runs locally in your browser and comfortably handles lists with hundreds of thousands of numbers. Very large lists may just take a moment to process.
