FAQ

Q: Does deduplication shuffle the original order?

A: No. It keeps the position and order of each card's first occurrence.

Q: Are differences in capitalization treated as duplicates?

A: Comparisons are character-exact. Different case counts as different content and is not merged.

Q: How are blank lines handled?

A: A blank line is treated as one entry and takes part in deduplication. To clean up blank lines first, use the "Trim Spaces & Blank Lines" tool.
