The only way to get Microsoft Excel is to buy Microsoft Office, which costs $400+. Using OpenOffice is another option, but few people know about this product, so they end up pirating a copy of Microsoft Office or trekking to their local computer store and spending a lot of money to solve a simple computing task. Starting today, the world has another option - ajaxXLS 0.5. This program, like ajaxWrite and ajaxSketch, is an AJAX program that loads in seconds directly over the Internet. One click on ajaxXLS.com and you have a spreadsheet program to open any .xls file. Nothing to buy. Nothing to install. No need to register.
