Importing data — Choose where the data goes

The import lands in your account, adding its tables alongside the ones already there so the new data can relate to them. Your account has one home for its data — see Folders, not separate workspaces — so there is no step here that splits it in two. If you opened the wizard from a workspace where you are an Admin, a Destination picker names that workspace explicitly and is selected for you. Editors and Viewers never see it, because adding tables changes the workspace's structure and that is reserved for Admins. A workspace is created for you only if you do not have one yet — an account that was invited into somebody else's workspace and has none of its own. In that case the Workspace name field prefills from your first file's name, and you become that workspace's Admin when the import finishes.
