Remove Duplicate Lines
Remove repeated lines from a list.
Questions
Which copy of a duplicate is kept?
The first one. Every later repeat is removed, and the remaining lines keep their original order unless you choose to sort them.
What do “Ignore case” and “Trim spaces” do?
With “Ignore case”, “Apple” and “apple” count as the same line. With “Trim spaces”, spaces at the start and end of lines are removed before comparing, so “apple ” and “apple” match too.
How does sorting handle numbers?
Numbers inside lines sort the way people expect: “item 9” comes before “item 10”.
Is it free? Do I need an account?
It is free to use and there is nothing to sign up for. There are no watermarks and no daily limits.
