Another good option for an example of an Excel file is Word. While Word documents are often less flexible when it comes to layout, they are still very easy to navigate through. You can just use the page up and page down keys to move the page around in order to get the layout that you want.
Using the example of a work breakdown structure template is a good way to get your data into the format that you need. Of course, if you want you can always look at Microsoft Word or Excel, but that will take a lot longer to download and you will be making mistakes in the process.
