I personally use Excel for all my collections, since it’s easy to use with, can be viewed online on Google Drive, and I can add formulas for totals.
I have a separated Excel for each of my main sub-collections:
And I also have an Excel of my entire collection of 11,000 unique cards, which are sorted by set release date.
And I haven’t kept track of when I purchased a certain card or what I paid for it. I honestly don’t want to see the exact amount of the 40k+ USD I already spend on my collections, haha.
For my other sub-collections I don’t use Excel that much:
- My National Index collection (including all forms and shiny Pokémon) can be found here (although I do have an Excel locally)
- My Moltres WotC #21 artwork (including sealed and graded) can be found here (although I do have an Excel locally)
- My Yu-Gi-Oh rarity collection can be found here, and I’ve used a text doc instead of Excel
