Frequently Asked Questions
You can upload .txt and .csv files for each list. Alternatively, you can paste or type items directly into the text areas, with one item per line.
When "Ignore case" is enabled, items like "Apple" and "apple" will be considered matching. This is useful when comparing lists with inconsistent capitalization.
You will see three result categories: Matching Items (items found in both lists), Unique to List 1 (items only in the first list), and Unique to List 2 (items only in the second list).
