We do not (yet) have a specific Export link for the Volunteer Schedule (that would create a PDF, CSV, or Excel file).

However, you should be able to get a similar effect by selecting the table on the web page (by clicking in the upper left corner of the table and dragging to the lower right of the table), and copy to the clipboard, and then pasting into an empty spreadsheet. 

You should be able to get a serviceable spreadsheet this way (different operating systems and browsers and spreadsheet apps may vary slightly in the method).

If you have difficulties, or need other functionality, please contact Support

(We will eventually have more tables exportable, but the above method usually works in the meantime)
