Sorting a list and removing repeats
Lines item 10, item 2, apple, item 2, with A to Z sorting and remove duplicates ticked
apple item 2 item 10 The message reads 4 lines in, 3 lines out, 1 duplicate removed.
The sort is natural, so "item 2" comes before "item 10", and the first copy of a repeated line is kept.
Sorting numbers highest first
Lines 3 apples, 12 pears, 7 plums, with the numbers highest first option chosen
12 pears 7 plums 3 apples The message reads 3 lines in, 3 lines out.
Lines are ordered by the number at their start, so text without a leading number would be placed after the numbered lines.
À propos de Sort Lines & Remove Duplicates
A line sorter puts a pasted list into order and tidies it at the same time. Sort alphabetically in either direction, by line length, or by the number each line starts with, or reverse or shuffle the list. You can also remove duplicate lines, trim stray spaces and delete blank lines, all in a single pass.
Sorting treats numbers inside text naturally, so item 2 comes before item 10. Duplicates are compared exactly unless you choose to ignore capital letters, and the first copy of a repeated line is the one kept. A short summary shows how many lines went in, how many came out and how many duplicates were removed.

Questions fréquentes
How do I remove duplicate lines?
Paste your list and leave the remove duplicates option ticked. Each repeated line is dropped and the first copy is kept. The summary beneath the box tells you how many were removed. Tick ignore capital letters if Apple and apple should count as the same.
How does alphabetical sorting work?
Lines are ordered using UK English rules, ignoring the difference between capital and small letters, and numbers inside text are compared by value. That means file2 comes before file10. Lines that differ only in case keep a steady order.
Can I sort numbers properly?
Yes. Choose Numbers, low to high or high to low. Each line is sorted by the number it starts with, including negatives and thousands separators. Lines with no number at the start are placed at the end, in alphabetical order.
What do trim and remove blank lines do?
Trim removes spaces and tabs from the start and end of every line, so lines that differ only by stray spaces count as duplicates. Remove blank lines deletes lines that are empty or contain only spaces, which is useful for pasted text with gaps.
Is the random order really random?
The shuffle uses a high-quality random number source, and every order is equally likely. Choosing Sort again shuffles the list afresh each time, which is handy for drawing names or deciding who goes first.
