Frequently asked questions

How do I remove duplicate lines? expand_more
Choose remove duplicates; you can ignore letter case if you prefer.
Does sorting understand numbers? expand_more
Yes. Natural sort puts 2 before 10, unlike plain alphabetical order which puts 10 first.
Does it keep Arabic and other scripts intact? expand_more
Yes, it works with any Unicode text.
Is there a size limit? expand_more
Only your browser's memory; tens of thousands of lines are fine.
