MobileSheets always requires local access to files. While you can import files from the cloud, they are downloaded to the device and stored in the MobileSheets storage location. If you changed the storage location to use the OneDrive folder (which I generally would not recommend as it can cause MobileSheets to be unable to access files if OneDrive locks them), then you would still be using local files, but the OneDrive automatic synchronization would just be downloading the files to the device for you in the background. Due to the limitations with the SQLite library for UWP applications (the database library), the MobileSheets database (mobilesheets.db) has to be stored in the default application directory, which is C:\Users\<your username>\AppData\Local\Packages\41730Zubersoft.MobileSheets_ys1c8ct2g6ypr\LocalState. So that file would not be synchronized by OneDrive (I just wanted to mention this in case you do try to leverage the Windows OneDrive application).
