Who grants sharing permissions in a Smartsheet account?

The correct answer is that the Sheet Owner grants sharing permissions in a Smartsheet account. The Sheet Owner has the ability to control access to the sheet, including who can view, edit, or share the sheet with others. This role is essential for maintaining the integrity and security of the data within the sheet, as it allows the Sheet Owner to determine how the information is shared and with whom.

In contrast, the other roles listed do not possess the same level of authority regarding sharing permissions. For example, a System Admin has broader administrative capabilities across the entire Smartsheet account, such as managing user settings and account configurations, but does not have the specific authority to grant access on a sheet-by-sheet basis. Similarly, an Account Admin has significant control over account-wide settings and user management, yet they typically do not hold the permissions to modify sharing settings for individual sheets. Finally, a Viewer role has the least control, as they can only view the sheet and cannot modify sharing settings at all.

Thus, the Sheet Owner's unique position as the creator or designated custodian of a sheet enables them to effectively manage sharing permissions. This detail reinforces the importance of understanding roles and permissions in Smartsheet for effective collaboration and data management.
