(06:42) Import Table from Text file.
(07:53) Although we can use PivotTable button from Manage Data Model window, we don’t have to use this button to have access to a Data Model for a new PivotTable. See how to access the Data Model using the normal “Create PivotTable” dialog box and the “Use an external data source” dialog button, “Choose Connection” button, “Table” tab in the Existing Connections dialog box, then click “This workbook Data Model”.
