What permission is required to hide and unhide columns?

To hide and unhide columns in Smartsheet, the user must have Admin permissions. Admins have the highest level of access, allowing them to make significant changes to the structure and visibility of the sheet, such as modifying columns or rows. This includes the ability to hide or unhide columns based on the needs of the team or project.

Although Editors can make changes to the content within a sheet, they do not have the ability to alter the overall structure, which includes hiding or unhiding columns. Similarly, Viewers only have read-only access and cannot make any changes, including adjustments to column visibility. Collaborators may have various permissions that allow them to edit or view, but they do not have the full access needed to manage column settings like an Admin does.

This tiered permission structure is essential for maintaining control over how data is presented in Smartsheet, ensuring that only users with the appropriate authority can modify visibility settings.
