Questions
Does the order of the lists matter?
No. Each item is matched wherever it is in the other list. Turn on Sort A to Z to sort the answers.
How do I compare two columns from a spreadsheet?
Copy each column and paste it into a box. Every row becomes one item, and each answer can be pasted straight back into a spreadsheet.
How are repeated items counted?
Each item appears once in the answers. The count under each box shows how many items are repeated in that list.
Are capitals and spaces ignored?
Yes. By default "Anna" and "anna" count as the same item, and spaces at the ends of an item or doubled inside it are ignored. Switch off Ignore capitals or Ignore extra spaces to match exactly.
Is my list uploaded anywhere?
No. The comparison runs in your browser with JavaScript. Our tools never upload what you paste.
Does it work offline?
Yes, once the page has loaded. The tool keeps working with your internet switched off, because it runs entirely in your browser.
