• Operations including: Set Intersections (AND), Set Unions (OR) and Set Differences between two lists
• Cut and Paste your lists into textbox A & B, then click Compare Lists to work out the differences between the two lists
• There are other functionalities that you can perform over the results of the comparison including:
