Click Save if you're adding it to your reports list, or Save & add if you're adding it to a dashboard.
In the pop-up box at the top, click Go to reports.
Hover over the Tasks incomplete assigned to all reps by activity date report, click the Actions dropdown menu, and select Export.
In the dialog box, enter a name for the export and click the File format dropdown menu to select the file format you want the export to be in.
