What is Text Cleaning?

Text cleaning is the process of transforming raw, messy text into clean, usable content by eliminating duplicates, whitespace issues, blank lines, and lines containing specific keywords. Writers, bloggers, SEO specialists, developers, and data analysts use text cleaners daily to save hours of manual editing.

Why You Should Remove Duplicate Lines

Duplicate lines appear in logs, exported databases, email lists, scraped content, and brainstorming notes. They bloat files, confuse readers, hurt SEO, and waste server resources. Our tool removes duplicates while preserving the original order of first appearance.
