How it works
Sort a list without losing sight of its cleanup rules
02
Choose explicit cleanup
Decide whether blanks, whitespace, duplicate values, and letter case should affect the result.
03
Review and copy
Check the output count and copy the exact LF-separated text you intend to use.
Clear limits
Sorting is not interpretation.
The tool orders visible text values with natural number ordering, so item 2 comes before item 10. It does not know whether two differently written values mean the same thing. Turn on each cleanup choice only when it matches your list.
Local processing
Pasted text stays in the current browser tab.
Natural order
Numbers embedded in lines sort in a human-readable order.
Explicit deduplication
Nothing is removed unless you enable duplicate removal.
LF output
The copied result uses a standard single line-feed separator.
FAQ
Common questions
What counts as a duplicate?
With case sensitivity off, uppercase and lowercase versions of the same text are duplicates. If surrounding-whitespace removal is on, that cleanup happens before duplicates are compared.
Why did blank lines remain?
Blank lines are retained by default. Turn on Remove blank lines when you want to omit them.
Does this upload my list?
No. Sorting and cleanup happen only in your browser.
