Excel Opens Completely Blank/No Menus

I have read here the answer from another thread, as I face the same problem -
Right click on the filename -> go to properties - on the bottom of 'General' tick the 'Unblock' box and you are done.
I don't know how to do it constantly on any file..

well that is just about the simplest and most effective solution now isn't it? that worked in terms of getting the file to open. but i still have no menus!

I think this is another issue, though might be caused by the same reason which caused the blocking.

well this was really the *main* issue, as it was less important that i couldn't open the files (i was able to download them as other file types and get the info i needed) than it is not being able to function in excel whatsoever. all i can do is type into cells and use whatever formatting available from keyboard shortcuts and the right-click menu.

*note: this only happened after trying to fix the original problem. it was something i did trying to open those files that caused this problem.

So try to re-repair the excel Sorry, just joking. If this is what happened maybe the best way is to uninstall and install Excel.
