I appreciate this post is 12 years old, but my team finally added this feature to Data Controller today!
Just upload the excel, enter the password, approve the change, and your password-protected excel data is now in your target SAS table ready to process. Works on ALL versions of SAS (Viya, EBI, Base) and is free for up to 5 users.
