I made this for personal use, but thought of sharing it with anyone who might find it useful.

This spreadsheet keeps track of what classified set item you have and don't have, and displays it in a user-friendly way so that when you get a new classified, you won't need much time to see if you already got it or not.

Download the file 1st before using it as it will not work using google sheets.
