I am building a new website for a friend of mine. Its all plain html, and a server side include. The problem is to build static pages for 500 products would not be fun to create, or maintain. So i am forced to at least put dynamic information on these pages based off a spreadsheet, or dynamic pages all together. What i want to do is have a spreadsheet that can be used to keep track of in stock quantity, sku numbers, ecc.. that way i dont have to update hundreds of pages every night. He can just edit the spreadsheet and the pages will automatically adjust. I am a busy man, and i am not asking anyone to just give me the answer. But to save some time what is more worth learning to get this done fastest. HTML5, PHP, JAVA asp, or is there somehthing else better suited?
