Remove Duplicate Text Lines for Free

Paste a list with one item per line and remove lines that exactly repeat an earlier entry. Inspect the resulting text before copying or downloading, since different capitalization or spaces still make two lines distinct.

Deduplicate a List While Keeping Order for Free

Use an ordered list as input to keep only the first appearance of each exact line. Check the remaining sequence against the source when order matters, and normalize unwanted whitespace beforehand if those differences should not create separate items.

Extract Unique Lines Online for Free

Enter repeated text lines to produce a list of distinct entries without sorting them. Review lines that look alike but remain separate, because exact matching preserves differences in letter case, leading spaces and trailing whitespace.
