How to Remove Duplicate Lines and Words from Text
Pasted a list with repeats, or a document with the same word over and over? Manually hunting duplicates is painful. Here's how to clean text quickly.
Duplicate lines
For lists (emails, URLs, keywords), removing duplicate lines leaves one of each, usually preserving order. This is invaluable for de-duping mailing lists, merged exports, or keyword sets before analysis.
Repeated words
Within prose, repeated words are a style problem — finding overused terms helps you vary your writing. A duplicate word finder counts and highlights the words you lean on too heavily.
Clean instantly
Our free remove duplicate lines tool de-dupes any list, and the duplicate word finder flags repeated words. To tidy formatting too, the remove line breaks tool helps.
Bottom line
Remove duplicate lines to clean lists, and find repeated words to sharpen prose. Both take one paste and a click — far faster and more reliable than scanning by eye, especially on long lists.
