How to use Filter a List of Numbers
- 1. Paste your list of numbers. Enter the numbers you want filtered, separated by commas, spaces or line breaks, into the input pane, for example 3, 15, 8, 22 and 10.
- 2. Choose the filter condition. Pick a rule under Keep numbers that are, such as Greater than value, Even, Odd, Integers or Decimals, and set Value if the rule needs a comparison number.
- 3. Copy the filtered numbers. Set the Separator for the output format, then copy the matching numbers, such as those greater than 10, from the output pane into your next step.
When to use Filter a List of Numbers
Filter a List of Numbers keeps only the values that match a condition you choose, whether that's a comparison against a threshold or a property like even, odd, integer or decimal. It replaces manually scanning a list for matches.
- Isolating outliers above a threshold. A dataset of measurements or sales figures needs every value above a specific cutoff pulled out for closer review, without writing a spreadsheet formula.
- Splitting a mixed list into whole numbers and decimals. A pasted list of numbers mixes integers and decimal values, and you need only the whole numbers for a step that can't handle fractional input.
- Preparing even or odd subsets for a puzzle. A number puzzle or classroom activity needs just the even values or just the odd values pulled from a longer list of numbers.
- Cleaning a data export before analysis. An exported column mixes valid and out-of-range readings, and filtering to values below or equal to a sensor's rated maximum removes bad readings before charting.

Frequently asked questions
Is Filter a List of Numbers free to use?
Yes, it is completely free. All 2,658 tools on EditSafely work without an account, a subscription or usage limits.
Is it safe to paste sensitive or confidential data?
Everything happens locally. Your browser downloads the tool's code once, then does all the processing itself; nothing you enter is transmitted, stored or logged. You can even go offline after the page loads and it will still work.
How much text can I process at once?
There is no fixed limit. Because the work happens on your own device rather than on a shared server, the practical ceiling is your machine's memory, which comfortably handles inputs far larger than typical online tools allow.
Do I need to sign up or install anything?
No. The tool works in any modern browser on desktop, tablet or phone. There is no account to create, no extension to add and no software to install.
How do I use the result?
The output panel has a one-click copy button, and you can keep refining the input while you work; the result updates in place as you type.
