Frequently Asked Questions
Is the comparison case-sensitive?
Yes, "Word" and "word" are considered different items. If you need them to match, convert both lists to lowercase first.
Can I compare more than 2 lists?
This tool compares two lists at a time. To find the intersection of 3 lists, find the intersection of A and B first, then take that result and find its intersection with List C.
