Data can be exported as a CSV file which can be opened in Microsoft Excel. This will show all of the session data on display in the particular filter, or the pageview data for all Sessions. Click the Export dropdown from the top bar, and upon clicking the Export as CSV button, you will be given the option of Sessions or Pageviews, before the download will be prepared in the Recent exports with "Pending" displayed under Action. Once this file is ready for download, the status will change and a Download, Edit and Delete icon will appear.
Recent exports will appear in the above list, while all Exports can be seen in Archives, which can be found by clicking Archive from the left hand menu, or clicking the Show archive button within export.
