There have been questions about command-line parameters but no postitive feedback. When investigating content in this website I was totally dumbfounded when I discovered we can't pass the user ID and password to a workbook* that requires such credentialling to just open it! For shame!
The attached document is the discovery of my findings. If anyone has more to add please let me know so I can make updates.
*Believe me, I tried all sorts of parameter names and syntax to see if one would work (--password, /pwd, -p, etc.). Nothing
