Frequently Asked Questions
Can I sort a numbered list?
Yes — numeric-aware sorting puts item2 before item10, which plain alphabetical sorting gets wrong.
Does it remove duplicates too?
This tool only sorts. For deduplication, use our Remove Duplicate Lines tool — the two work great together.
Will blank lines break the sort?
Blank lines sort to the top; delete them first or leave them — they won't corrupt your data.
How many lines can it sort?
Thousands of lines sort instantly in your browser.
Is it free?
Yes — free forever, no signup.
