How to remove repeated list entries
- Paste one name or item per line, or load the sample. Blank lines are skipped.
- Choose whether to trim surrounding spaces and ignore case, then remove duplicates. Editing the input or matching options clears the previous result.
- Review the total, unique, and removed counts. Copy or download the unique list, then paste it into the name picker, team generator, or list randomizer.
Prepare lists for everyday draws
- Remove accidental repeated sign-ups before a name draw. Check whether identical names belong to different people before removing them.
- Clean a participant list before dividing it into teams.
- Review repeated task labels before shuffling a task list.
Frequently asked questions
Which entry is kept?
The first matching entry is kept, and the original order is preserved. Trimming is on by default; case matching is sensitive by default. With case ignored, the spelling of the first entry is retained.
What counts as a match?
The tool compares whole lines after applying your selected trim and case options. It does not collapse internal spaces or normalize fullwidth characters, accents, or other Unicode variants. LF, CRLF, and CR line endings are supported; blank lines are always discarded.
Should I remove every repeated name before a draw?
Review the list first. Different people may share a name, and some draws intentionally allow multiple entries. Add an identifier when people need to remain distinct.
What does the repeated-items view export?
The view shows each repeated item with its total occurrence count. Copy and download include each such item once on its own line, without counts.
Are my entries sent to the other tools?
No. Processing happens in this browser tab. To use the result in another tool, copy it and paste it there yourself. Input and output contents are not included in analytics events.
