Replacing an xlookup with a better way? Database?

I have this file that I reference all the time for work, and it has like a listing of all our stores, new, old, and projected, and then all their details (sqft, opening date,etc). I would like to stop using xlookups every single time I want to get the store details and use something more sophisticated. Now the details of our stores change quite often, with renovations, closures, etc, so whatever we use next has to be easy for a user to go in and change it. What do you suggest?
