I'd recommend watching this YouTube video; it's only one person's take on the right way to use Excel, but Excel has many ways to handle these issues:
I sincerely wish it had a different name, though!
I would love to send this video to some of my business colleagues inside a large enterprise. They need this information and they would enjou everything about this video. However, it would not be acceptable to send them a video entitled "You Suck at Excel."
If it had a more enterprise-friendly name I would even have a link and description to it in my email footer inside the enterprise. It would really help a lot of people.
Update: okay check out https://excel.secretgeek.net/
I've re-badged it as "Secrets of Mastering Excel" and used absolute positioning to put a label to that effect over the video's title.
Ideally I'd detect when the video starts and remove the label. Hmm. Not sure of the right approach.
I recommend (at the foot of the page) that the viewer watch it in full screen (which will remove my dodgy title)
