About Remove Duplicate Lines
Lists collected from different sources almost always contain repeats. This tool removes duplicate lines from any text in a single click, keeping the first occurrence of each entry so your list stays in its original order. Options let you treat different capitalisation as the same, ignore leading and trailing spaces, drop blank lines and sort the cleaned result alphabetically.
It is handy for de-duplicating mailing lists, keyword research exports, log files, product SKUs, URLs from a crawl, or the contents of a spreadsheet column. Paste, click, copy: no formulas required.
How to use the Remove Duplicate Lines
- Paste your list or text into the input box, one item per line.
- Choose options: ignore case, trim whitespace before comparing, remove empty lines, or sort the result.
- Click Remove Duplicates. The cleaned list appears below with a count of how many lines were removed. Copy it with one click.
