Any view in TrackVia can be exported to Excel.  If you would like to export only certain records and/or fields you should first build a Custom View that returns the data you'd like to export.  Once you have a view you can run this and choose the "Excel" option from the format drop down list that appears in the upper right corner of each view to send this to a spreadsheet.  If nothing happens when you select this option you might need to disable any pop-up blocker you have active.
