Tips for using the list comparison tool

With this online tool you can compare lists of words and lists of numbers. I didn't add any unnecessary functionality to the tool. Only the comparison of lists.

Operations including:

  • Set Differences
  • Set Intersections (AND)
  • Set Unions (OR)
  • Symmetric difference

You can compare lists without or case-sensitive. To do this, use the "Case Sensitive" option above the "Compare lists" button. The "Ignore Begin End Spaces" option is useful if you want to ignore spaces at the beginning and end. Use the "Copy", "Clear" and "Sort" buttons if you want to copy, clear or sort the lists.

The tool works on desktops and smartphones. I hope you will find this tool useful.
