Which user type should a System Admin assign to a user who needs to view and edit sheets?

The appropriate choice for a user who needs to both view and edit sheets in Smartsheet is the Editor. An Editor has the necessary permissions to not only see the contents of sheets but also make changes to them, such as adding, modifying, or deleting data. This role is essential for individuals who are involved in collaborative work and need to actively participate in the document's content.

For instance, if a user is assigned as an Editor, they can contribute to project updates, adjust timelines, and manage other elements within a sheet. This level of access supports effective teamwork, especially in environments where continuous updates and revisions are necessary.

The other user types—such as Unlicensed User, Resource Viewer, and Commenter—do not provide the same level of access. An Unlicensed User cannot interact with sheets at all, a Resource Viewer only has the ability to view resource-related information without making edits, and a Commenter can leave comments on sheets but cannot modify any of the data. Thus, these roles would not fulfill the requirements of someone needing to edit sheets actively.
