Tips for Cleaner Lists

  • Trim option: Enable trimming to collapse variations like apple and apple into one line.
  • Sorting: Sorting unique lines makes it easier to scan results when order doesn’t matter.
  • Case sensitivity: Disable match case to treat Item and item as duplicates, or enable it to keep variants.
  • Duplicates panel: Keep it visible to understand which lines were removed and how often they appeared.
