Rename workbooks on Tableau Online or Tableau Server
The latest Tableau Desktop 10.5 Update is utterly awesome. Now you can rename workbooks on Tableau online or Tableau server, like butter!
There’s no need to republish workbooks just to rename them. Now you can rename workbooks directly on Tableau Online or Tableau Server. When you do, workbook URLs remain the same, so any links you’ve shared keep working. Navigate to the main Workbooks area, click the pop-up menu in the upper-right corner of a workbook, and select Rename. To rename a workbook, users need the Save permission. You’ll have that by default for workbooks you own, but you might need to add it for other users. For details, see View or Edit Permission Rules in Help for Tableau site administrators.
