I am used to viewing files in different windows and when I found Excel forcing me to view two spreadsheets inside the same MDI form I looked for an alternative.

Realistically I thought that an option would be available allowing me to choose how Excel opened multiple documents but I was wrong.

If you want to open two Excel files in different windows for whatever reason, you need to modify the File Association actions.

Since I use dual monitors on a daily basis, this "fix" is a must in order to take advantage of having a dual display.

The answer can be found in the following article: Open Excel in Different Window
