I have worked with Excel spreadsheets for years and though I know a lot about them. Then I started my PC on it. It looked good until I started to get more and more cards. As it grow to over 23,000 cards the titleing became a problem. Where I got information about the cards diff form site to site.I was down loading cards from several sites. When I down loaded stuff the hiden information about the row and collumin was included so sorting looked like hell. After years of fine tuning I have it closer to be done. I have done a lot of changes to match what is here. Still have more to go. Some of the newer sets has base, Auto, and jersey cards in them. I have them broken away from the base. It do not help when I deleted the word "Autograhs" form file.
Plus I have close to 500 cards that are not allowed here.
