So does that mean if you send somebody a workbook they have access to the sheets/dashboards but not to the underlying data that feeds in?
If you send a TWBX then they will have access to everything. All they need to do is unzip the TWBX into a TWB and its associated folder which contains the underlying data.
Thanks Jason. So if you just send someone just a TWB they can't access the underlying data?
Yes that is correct.
