File|Export|Outcome file
The Export Outcome command creates a data file using the outcomes stored in the markbook for use in other applications. Click on the Download CSV File button to download the exported data with your browser. Depending on how your browser is configured to file may be opened automatically, or put into your Downloads folder.
The data is exported as a zip archive with a name based on the name of the markbook and the current date. After the download is complete, click on the Return to Markbook button.
All outcomes are exported, but if any outcomes are tagged only those outcomes are exported.
