By default, duplicates are detected case-insensitively. Enable case sensitivity to treat 'Apple' and 'apple' as different items.
Leading and trailing whitespace is trimmed by default. This ensures that 'apple' and ' apple ' are treated as the same item.
The first occurrence of each unique item is kept, maintaining the original order of your list.
Empty lines are automatically filtered out, keeping your cleaned list tidy and readable.
