Exporting analytics is a very simple process. To export Analytics, navigate to the analytics page of the program you would like to export and select the particular metric you would like to view. The current available metrics for export are reach, views, engagements, ROI, and channel details.
After navigating to that page, scroll down until you find a button titled either "Export CSV" or "Export Excel". Clicking this button will generate a spreadsheet that contains all the data that is displayed on the current page you are looking at.
If you would like to export analytics from more than one program, the process is almost exactly the same. The only difference is first you must navigate to the Analytics tab located at the top of the screen and select the different assignments from the Assignments text field. From there simply click show and proceed to export analytics exactly as laid out above.
