About This Free Online Extract Unique List Items
Our free unique list extractor removes duplicates from a list and returns only the distinct items, keeping one copy of each value. Paste your list, one item per line, and the tool deduplicates it instantly, leaving a clean set of unique entries. It is invaluable for tidying email and contact lists, combining data from multiple sources, building distinct value sets for spreadsheets and databases, and cleaning up survey or form responses. You can choose whether to ignore case and trim whitespace so that near-identical items are treated as the same, and the original order is preserved. Copy the unique list with a single click.

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.
