Duplicate Line Remover: Clean Lists Instantly
What Is a Duplicate Line Remover?
A duplicate line remover scans text line by line and keeps only the first occurrence of each unique line. It is useful for cleaning email lists, URLs, keywords, log excerpts, and any pasted data where repeats should be dropped.
The XSular Duplicate Line Remover runs entirely in your browser. Your text is never uploaded to a server.
How to Use This Tool
Paste your list into the input area—one item per line. Choose whether matching is case sensitive, whether to trim spaces before comparing, and whether to remove blank lines. Optionally sort the remaining lines A–Z or Z–A.
Use Live mode for instant updates, or switch to On click and press Remove duplicates when you are ready. Copy the result or download it as a .txt file.
