TEXT TOOL · CLIENT-SIDE
Duplicate Line Remover
Remove duplicate lines from text. Options for case sensitivity, whitespace trimming, and sorting.
How It Works
The tool splits your text into lines and compares each one. Only the first occurrence of each unique line is kept. With trimming enabled, leading and trailing whitespace is removed before comparison. With sorting, the output is arranged alphabetically.
Case Sensitivity
Toggle whether "Hello" and "hello" are treated as the same line.
Whitespace Trimming
Ignore leading and trailing spaces when comparing lines.
Sort Output
Arrange unique lines in alphabetical order.
Frequently Asked Questions
How does the duplicate remover work?
Paste your text and click Remove Duplicates. The tool compares each line and keeps only the first occurrence of each unique line. Options let you toggle case sensitivity, whitespace trimming, and sorting.
What does case-sensitive mean?
When case-sensitive is ON, "Hello" and "hello" are treated as different lines. When OFF, they are treated as the same and one is removed.
Can I sort the results?
Yes. Toggle the sort option to arrange unique lines alphabetically. This is useful for creating deduplicated, ordered lists from messy input.
