Remove Duplicate Lines

Quickly paste text from a file into the form below to remove all duplicate lines from your text.

This tool will compare all the lines in your text and then find and remove all of the identical lines. You can then paste the newly cleaned unique text lines back into a file for saving.

I've also added an option for you to alphabetize the lines after all the duplicate lines have been removed. You can also automatically sort the remaining lines in reverse order if you need to.

Note: Although the form below may seem small, you can paste tons of text into it to get your duplicate lines automatically removed. No problem.
