About
Removes repeated lines while keeping only the first occurrence, perfect for cleaning lists and spreadsheets.
How to remove duplicate lines from a text
Lists pasted from multiple sources often contain repeated items. The UtilNexo tool identifies and removes duplicate lines, returning a clean list in seconds.
Each line of text is compared with the others. The tool keeps only the first occurrence and discards repeats, preserving the original order of items.
Removal considers exactly equal lines (case-sensitive). Lines that differ only by spaces or case are not treated as duplicates.
It is ideal for cleaning lists of emails, names, tags, URLs, and any content with one item per line. Everything happens locally in the browser, with no text sent to any server.
Examples
- List "apple / banana / apple / grape" → "apple / banana / grape".
- List "Banana / banana" → "Banana / banana" (uppercase and lowercase are treated as different).
Limitations
- Lines with identical content but spaces in different places (for example, "apple" and " apple ") are not considered duplicates.
- Removal preserves the first occurrence; if item order matters, check whether the kept position is the one you want.
