How does the duplicate remover work?
▼
It processes your text line by line, keeping only the first occurrence of each unique line. Duplicate lines are removed while preserving the original order.
Is the comparison case-sensitive?
▼
By default, yes. 'Hello' and 'hello' are treated as different lines. You can toggle case sensitivity off to treat them as duplicates.
Can I remove empty lines too?
▼
Yes. Enable the 'Remove empty lines' option to strip out blank lines along with duplicates.
