FAQ
- How does case-insensitive deduplication work?
- When enabled, lines are compared after converting to lowercase, so "Apple" and "apple" count as duplicates. The first occurrence (in its original casing) is kept.
- What does "trim lines" do?
- Trim removes leading and trailing whitespace from each line before comparing. " hello " and "hello" are treated as the same line. The trimmed version is written to the output.
