I want to share Excel files in a SharePoint library.
The users shall only be able to open the files in "Excel Online", but not to download them or the open them offline. Also the original file shall not be changed.
I've solved that by assigning permission level
Nevertheless the users shall be able to use the basic Excel functionality (e.g. change cell values for doing calculations).
Is it possible to comply with point 2, without infringing point 1?
