Duplicate Line Remover is now live on Tools.Town — a fast utility that strips repeated lines from any block of text, with options for case sensitivity, blank-line removal, and sorting the output.
Paste a list of emails, keywords, URLs, or any line-based data, remove the duplicates, and copy the clean result.
What Does It Do?
Remove Dupes
Scans every line and keeps only the first occurrence of each unique line.
Sort Output
Optionally sort the de-duplicated lines alphabetically (A–Z or Z–A) after removing duplicates.
Stats Report
Shows original count, unique count, and how many duplicate lines were removed.
Toggle case-insensitive mode to treat ‘Email@domain.com’ and ‘email@domain.com’ as the same line — useful for email and URL deduplication.
How It Works
Paste your list
Paste any text with one item per line — emails, URLs, keywords, product names, anything.
Set options
Choose case sensitivity, whether to remove blank lines, and whether to sort the output.
Copy clean output
Click Copy to grab the deduplicated list, with a count of how many lines were removed.
Why We Built It
Deduplicating a list is a tiny task that comes up constantly — cleaning email lists, deduplicating keyword exports, merging two lists without repetition, or fixing copy-paste artifacts. Writing a script or opening Excel for this is overkill. A single-purpose tool handles it in seconds.
