Microsoft Office Excel 2007 has a new design that makes your work easier, faster, and more efficient. The new Ribbon puts the commands you use most often in plain sight on your work surface instead of hidden in menus or dialog boxes. Ready-made cell styles let you quickly format your worksheet to make it easier to read and interpret. The new Page Layout view shows how your printed worksheet will look as you're creating it.
