What does the Sort Lines tool do?
Alphabetical sorting with a twist that plain sorts get wrong: natural ordering, so “item2” comes before “item10” instead of after it.
Sort ascending or descending, optionally dropping duplicates in the same pass.
How to use the Sort Lines
- Paste your lines.
- Pick the order and options.
- Click Sort Lines and copy the result.
Frequently asked questions
What is natural number ordering?
Numbers inside text sort by value: file2 before file10. A plain character sort puts file10 first, which is rarely what you want.
Is the sort case-sensitive?
No — “apple” and “Apple” sort together, using locale-aware comparison.
Can I sort and dedupe in one go?
Yes — tick Remove duplicates.
Does my list leave the browser?
No — sorting is local.
