Method & assumptions
How Duplicate Line Remover derives its result.
Formula
Lines are compared in order using a comparison key determined by trim and case options. First occurrence wins.
Recommended workflow
- Paste one item per line.
- Select case and whitespace rules.
- Check output for entries that should remain distinct.
Limitations
The tool compares complete lines, not semantic equivalence or columns within a spreadsheet.
For important work, verify assumptions against the authoritative source for your task.
