常见问题
Is the comparison case-sensitive?
Items are compared by their exact text, so "Apple" and "apple" are treated as different entries. Trim and lowercase your lists first if you want a case-insensitive comparison.
What's the difference between the three modes?
Union combines every unique item from both lists. Intersection keeps only items that appear in both. Difference keeps items from list A that are not in list B.
