He not only has a spreadsheet but a whole cupboard in his mind palace where he stows them, along with any/all pertinent information about them: you know, their addresses, internet browsing history, other Tinder chats they’re still carrying on while seeing John, particular tidbits of their personal past that could, say, be used for leverage in a pinch. Unresolved feelings for exes. Allergens. What’s in the drawer of their nightstands. You know: just the basics.
