Remove duplicate lines from text lists
Clean repeated values and keep only the first unique appearance of each line.
Duplicate lines appear in many text workflows: exported tags, keyword lists, contact records, category tables, copied logs, and manually combined spreadsheets. Removing repeats by hand takes time and often causes accidental deletions. This page removes duplicated lines automatically while preserving one copy of each value, helping you produce cleaner lists for import, publishing, or analysis. You can also switch to sorting mode to arrange unique values alphabetically before exporting.
The tool works directly in your browser and does not upload list content. That matters when your lines include internal labels, campaign terms, or confidential identifiers. Paste data, choose the desired operation, and review output in real time. For downstream formatting, use internal links to convert line breaks, apply case formatting, or run developer encoding operations. The full flow remains client-side for faster turnaround and better privacy.
Ready.
Example
Input: apple banana apple cherry banana Output: apple banana cherry
