Export to Excel - widgets

I am trying to export data that is displayed in a Timeline widget and use it into a spreadsheet for graphing purposes. I have formatted these as resource demand, whereby the widget pulls resources (defined persons) for a task and rolls this up to a total (shown per week). I would like to be able to use the rolled up totals per week into a spreadsheet to graph them out. The Export to Excel, looks like it just exports the widget to a formatted graphical representation in a spreadsheet format with colors showing essentially a Gantt chart, which I cannot use to roll up totals. Unless I am missing how I can do this.
