Sorting lists, names and numeric data
Use numeric sort for lists of numbers so "10" comes after "9" instead of before it lexically, and the unique option to sort and deduplicate in one step.

Tips for better results
Keep a backup of original input before bulk transforms. Invalid input should show an error instead of silent corruption.
Privacy and offline-friendly processing
Whenever possible, Sort Lines processes your data locally with JavaScript in this page. That means drafts, secrets, and unfinished work stay on your device by default. Prefer this workflow when you do not want to upload sensitive text, tokens, passwords, or files to a third-party service.
Frequently asked questions
What is the difference between alphabetical and numeric sort?
Alphabetical sort compares lines as text ("10" sorts before "2"), while numeric sort compares their numeric value ("2" sorts before "10").
Can I sort and remove duplicates at the same time?
Yes, enable "unique only" to deduplicate lines before sorting.
Is my data uploaded when I use this tool?
For most FlyUtils tools, no. Processing happens in your browser with JavaScript. If a tool ever needs a server, that will be stated clearly on the page.
Is Sort Lines free to use?
Yes. Sort Lines is free, with no sign-up and no artificial usage caps for normal personal and work use.
Does Sort Lines work on mobile?
Yes. The page is mobile-first, so you can paste input, tweak options, and copy results from a phone or tablet.
