Useful Tools & Suggestions:

If you’re comparing two lists, Find Common Items in Lists is perfect for quickly spotting overlaps. On the flip side, Find Distinct Items in Lists helps you zero in on what’s unique to each one. Before you run either, it’s smart to Remove Duplicate List Items so you’re working with clean, meaningful data. That combo makes comparisons faster, easier, and a whole lot clearer especially when you’re juggling long or messy inputs.
