Its great! And you can really fill up an Excel worksheet quickly... But for those that really get into it, traversing a massive Excel sheet can get pretty daunting. The resolution to this for some people is to create other Excel files in a static location that all reference each other. That works, and is ok for some purposes, but not always. I would NOT recommend breaking out an Excel sheet into multiple linked Excel sheets just for ease of navigation sake. Once you hit the 4th or 5th linked Excel file and have more than one person trying to figure it out, good luck.
An alternative approach
A little known trick to quickly navigate multiple Excel worksheets, much like a table of contents, is to right click on the arrows in the lower left hand side of the application (to the left of the worksheet tabs). This will open a form called 'Activate'. 'Activating' a worksheet just means that it will be navigated to. Its not really activating or enabling anything. The terminology is a little odd but thats all its saying. This is basically a table of contents for your Excel file!
I had a worksheet with over 50 tabs and could navigate to a specific one in three clicks (right click on arrows, select worksheet, click ok). You might need to scroll to the worksheet if there are a lot but thats easier than the alternatives or a table of contents workbook tab.
Hope that helps!
