Duplicate lines remover
What deduping lines does
Collapse repeated rows in logs, survey exports, or keyword lists so only unique lines remain—often showing how many lines were removed. Two lines that look identical may still differ by trailing spaces, invisible Unicode, or Windows versus Unix line endings; normalize in your editor if counts surprise you.
When to use it
After Text separator or before List alphabetizer when order no longer matters but cardinality does. For fuzzy dedupe (same URL with utm_ noise), prefer specialized cleaning—not this exact-line tool.
