You can store the whole library information in excel. You just need to create 3 additional stuff. A database in excel, a dblib to describe the excel for altium, schlibs for the schematic parts and pcblib footprints. I dont think anyone has a good way of explaining how to do it, this is something everyone has to do only once in their life, and the trivial methods are only for the vaults, and inlibs. If you cannot figure it out how to do, I would contact altium support.
