Open file in Excel 2016 using AppleScript

Question

In Excel 2016, the following AppleScript:

tell application "Microsoft Excel"
    activate
    open "Macintosh HD:Users:path:to:file"
end tell

opens a dialog asking the user to grant access With previous Excel's versions, the file opened immediately. It seems that Microsoft doesn't allow any more to open a file from a script without the express user permission.
Is there a way to bypass the dialog?

Answer 1

Use a file object or an alias object instead of a string

tell application "Microsoft Excel"
    activate
    open file "Macintosh HD:Users:path:to:file"
    -- or --> open alias "Macintosh HD:Users:path:to:file"
end tell

When you have a POSIX path, you can use this (open POSIX file "..." doesn't work)

tell application "Microsoft Excel"
    activate
    set my_file to POSIX file "/Users/name/path/to/file"
    open my_file
end tell

Answer 2

This opens the selected files

tell application "Finder"
    open selection with MicrosoftExcel
end tell

Answer 3

I use this scriptlet to work around the access permissions dialog:

'with timeout of 10 seconds
    try
        -- File open may time out due to Apple's sandbox security rules. 
        open FileName
    on error        
        -- A Cancel and Grant Access dialog pops up and stops execution. Click the Grant Access button.
        tell application "System Events" to tell process "Microsoft Excel" to tell button "Grant Access" of window "Open" of application process "Microsoft Excel" of application "System Events" to perform action "AXPress"
    end try
end timeout'
