Remove duplicate lines
Paste a list and keep each line once.
How to remove duplicate lines
- Paste your list, one item per line.
- Choose the options you need: Ignore case, Trim spaces, Remove empty lines or Sort A to Z.
- Press Clean list and read the result.
- Press Copy and paste it where you need it.
What each option does
- Ignore case treats Apple and apple as the same line. The first one you wrote is the one that stays.
- Trim spaces removes spaces at the start and the end of each line, so a line with a stray space is not counted as different.
- Remove empty lines deletes blank lines between items.
- Sort A to Z puts the list in alphabetical order after the duplicates are removed. Leave it off to keep your original order.
Common uses
- Clean an email list or a list of names before you import it.
- Remove repeated keywords from a keyword research list.
- Make a list of unique URLs, IDs or product codes.
- Shorten a log file by keeping each repeated message once.
Good to know
Two lines are duplicates only when they are the same after the options you chose, so check spaces and capital letters if a duplicate stays. Very large lists depend on your device, and your list is never uploaded.
