Frequently asked questions
- How does duplicate detection work?
- Lines are compared exactly. The first occurrence is kept and any later identical line is removed, preserving the original order.
- Does it ignore extra whitespace?
- By default no — 'apple' and ' apple' are treated as different. Trim each line before pasting if you want whitespace ignored.
- Is the comparison case-sensitive?
- Yes. 'Apple' and 'apple' are kept as distinct lines.
- What's it good for?
- Cleaning email lists, deduplicating URL exports, tidying keyword lists, and pruning repeated log entries.
