How to Use
- Paste or type your text into the input box — each line is treated as one item.
- Choose your options: case-sensitive matching, whitespace trimming, and whether to keep the first or last duplicate.
- Click Remove Duplicates to process the text.
- Copy the cleaned output with the Copy Output button.
Case-sensitive means "Apple" and "apple" are treated as different lines. When off, they count as duplicates. Trim whitespace ignores leading and trailing spaces when comparing lines.
