By opening the file in Excel, you can sort by Last Login Date or create a pivot table to see if users haven't logged in for 12 months which may indicate they no longer require a license.
From the Workspaces tab you can access the workspaces.csv report. You may find it useful to use the Created Date to sort workspaces by age and confirm if they are still required with the workspace managers. Excel can be used to sort the report by Created Date.
