Microsoft Excel is a spreadsheet program that allows for people to share information in an orderly fashion. It features calculation, graphing tools, and pivot tables. Microsoft Excel uses a programming language called visual basic. It would be recommended to seek out a tutorial or even a class if you are looking to get the most out of Microsoft Excel and learn how to use it fully.
One quick tip, however, is that if you are looking to make a text more visible without losing data you should use the wrap text feature. This will allow you to see the full amount of text you are trying to display.
