Excel does many useful things and entering data so that you can do calculations or manipulate data. However, sometimes you need to bring that data in from somewhere else or you need to export it to be used in another application.

Excel also lets you export to these text based formats too.
Thankfully, Excel does this with ease. Here are two video tutorials to show you how to do either.
