Whether your file is in the cloud or a local network drive, Microsoft has tools to enable you to prevent unauthorised opening, editing and downloading of your data.
Securely sharing Excel files and preventing editing and downloading is possible through the use of a cloud-based collaboration platform. These platforms provide a secure environment where files can be shared, edited, and downloaded without any risk of the data being compromised. With these systems, users can set permissions that restrict who has access to the files, and what level of access they have.
