Remove Duplicate Lines from Text
Our duplicate line remover is a simple but powerful tool that helps you clean up lists, data exports, and any text with repeated lines. Whether you're working with email lists, product catalogs, or log files, this tool makes data cleanup quick and easy.
How It Works
The tool scans through your text line by line, keeping track of lines it has already seen. When it encounters a duplicate, it skips it. The result is a clean list with only unique entries.
Options Explained
