Pro Tips

Case Sensitivity

By default, duplicates are detected case-insensitively. Enable case sensitivity to treat 'Apple' and 'apple' as different items.

Whitespace Handling

Leading and trailing whitespace is trimmed by default. This ensures that 'apple' and ' apple ' are treated as the same item.

Order Preservation

The first occurrence of each unique item is kept, maintaining the original order of your list.

Empty Lines

Empty lines are automatically filtered out, keeping your cleaned list tidy and readable.
