Remove Duplicate Lines — free online tool
You copy a long list from somewhere, and half of it repeats. Same email twice, the same word over and over, rows you've already got. Cleaning that by hand is slow and easy to mess up. We added a free tool that does it for you — Remove Duplicate Lines — right in your browser.
What it does
Paste your list, and it removes any line that shows up more than once, so you're left with one of each. It can also sort the lines in order, so the cleaned list is tidy and easy to read.
Nothing leaves your device
It all runs inside your browser. Your list isn't uploaded anywhere, nothing is saved on a server, and nobody else sees it. When you close the tab, it's gone.
How to use it
- Open Remove Duplicate Lines and paste your list into the box.
- Let it strip out the repeats, and turn on sorting if you want the lines in order.
- Copy the clean list and use it wherever you need.
It's free with no limit. There are more small tools on the Apps page.
