Here's a solution. Use Google sheets. I use it almost exclusively for workbooks I use regularly. Collaboration is seamless. I can access my sheets anywhere, anytime, any platform. It doesn't have all the pretty bells and whistle, but for basic spreadsheeting, it's fine.

And if paying a support charge bugs you, you'll like this part. It's free.

The only reason I have Office is because it came with the laptop. I come to the forums just to pass the time, hone my skills, and learn a thing or two.
