How It Works

Our deduplicator is built for speed and flexibility. It processes your input based on your chosen settings and provides a clean output instantly.

  3. Get Your Clean List: The unique items appear in the output box on the right, along with detailed statistics about the process.

Key Features

  • Multiple Deduplication Modes: Define what constitutes an "item" in your text.
    • Lines: Treats each new line as a separate item. Perfect for lists.
    • Words: Treats each space-separated group of characters as an item.
    • Characters: Treats every single character as an item.
  • Powerful Filtering & Sorting Options:
    • Case-Sensitive: A toggle to decide if "Apple" and "apple" are treated as duplicates or as unique items.
    • Trim Whitespace: Automatically remove leading and trailing spaces from each item before comparison, ensuring " item" and "item " are treated as the same.
    • Sort Before Processing: An option to sort the entire list alphabetically before removing duplicates. This ensures your final unique list is also sorted.
  • Live Mode: Enable this for a real-time experience. The output and statistics will update instantly as you type or change any setting.
