You can restrict workbook access, but it depends on your plan. For Enterprise users: go to your workbook title → "Edit workbook settings" → under "Edit Access" select "Workspace admins and specific collaborators" → add only the users who should have access. [1]
Unfortunately, table-level restrictions aren't supported - once someone's in your workspace, they can view all tables/workbooks. For non-Enterprise plans, workbook-level restrictions also aren't available.
The main workaround is controlling who gets invited to your workspace in the first place through Settings → Team.
You're right - workbook access restrictions are only available on Enterprise plans. If you're on a free, starter, explorer, or pro plan, you won't see the "Edit workbook settings" option I mentioned.
For non-Enterprise plans, your only workaround is controlling workspace invitations through Settings → Team, since everyone in the workspace can see all tables and workbooks.
Exactly right - workbook access restrictions are Enterprise-only features. On Pro plans, your only option is controlling who gets invited to your workspace through Settings → Team, since everyone in the workspace can see all tables and workbooks. [1]
Unfortunately there's no workaround for table or workbook-level privacy on non-Enterprise plans.
If you need any more help with managing access on your Pro plan, please let me know. Would you like to share more about what you're trying to achieve so I can assist further?
