What feature would a System Administrator use to restrict what users can see?

Filters are a powerful feature within Smartsheet that allow a System Administrator to limit the visibility of data to specific users based on defined criteria. By applying filters, the administrator can ensure that users only see the information that is relevant to them or that falls within their designated permissions, creating a customized view of the data.

When filters are applied, they can hide or show rows based on certain attributes, such as tasks assigned to a particular user or status of projects. This way, users are unable to see all the information in the sheet but only what's pertinent to their roles or needs, enhancing privacy and focus.

Using other tools like reports, dashboards, or formulas does not inherently provide the same level of restriction on visibility. Reports aggregate and display data from multiple sheets, which doesn't restrict view but rather presents information across various sources. Dashboards serve as visual representations and summaries of data and can display information widely rather than restrict it. Formulas calculate values or derive information but do not directly impact what can be seen by users in terms of visibility control.

Thus, filters are the most effective method for a System Administrator to manage the visibility of the data, ensuring users can access only the information that is appropriate for them.
