It is quite normal for people to only install Word from the Microsoft Office suite, and leave the rest because they never use them, and Excel is no exception. Why are you going to install such a large program when you never use it? However, what happens if suddenly you have to look at a .xls Excel document?In this case Microsoft have created Excel Viewer 8.0, which is a simple viewer for any document done in Excel without the need to have the gigantic Microsoft Excel program installed.Practical, useful, functional and above all without consuming resources or occupying space.
