What it does
Sort lines of text with optional dedup, trim, and natural ordering (file-2 sorts before file-10, the way you’d expect). Six modes — A→Z, Z→A, natural, length ascending, length descending, and shuffle — cover essentially every "I have a list and need it ordered" need.

Frequently asked questions
- What's natural sort?
- Natural sort treats numbers in strings as numbers — so 'file-2' sorts before 'file-10', not after. Standard alphabetic sort puts '10' before '2' because '1' < '2' as characters.
- Will this preserve duplicates?
- By default yes. Tick 'Remove duplicates' to dedupe before sorting.
