Frequently Asked Questions About Extract Unique List Items
What is the difference between Unique Only and Keep Singles?
Unique Only deduplicates the list, keeping the first occurrence of each item. Keep Singles removes any item that appears more than once, keeping only items that appear exactly once in the original list.
Does the case-sensitive toggle affect output?
Yes. When case-insensitive is on, "Apple" and "apple" are treated as the same item. The first occurrence's casing is preserved in the output.
