How to use Remove duplicate lines
Clean repeated entries out of a line-separated list while keeping the original order of the first occurrence. Matching uses the complete line, including its case and spaces. If entries differ only by extra spaces, tidy the spacing first when you want them treated as duplicates.
01
Paste one entry per line
Add the list containing repeated entries.
02
Remove exact duplicates
Generate the cleaned list using case-sensitive, whole-line matching.
03
Copy the cleaned list
Review the retained entries and copy or download the result.
COMMON QUESTIONS
Remove duplicate lines: useful answers
Are Apple and apple treated as duplicates?
No. Matching is case-sensitive, so those are separate entries. Convert the list to a common case first if required.
Does this sort the list after removing duplicates?
No. It keeps the first occurrence of each exact line in its original position. Use Sort lines for alphabetical output.
