I found and have been able to implement a macro from this thread which lets me export multiple tables and save them into dynamically named workbooks. It works great, except that I want to modify it so that it can save the data to preexisting workbooks instead of creating new ones so that I can run macros in them and spit out the data in a report.
Here's the code as I currently have it set.
sub Export
set f = activedocument.Fields("Brand")
if IsEmpty(f.GetSelectedValues) then
set pv = f.GetSelectedValues 'adds selected values if any
else
set pv = f.GetPossibleValues(1000) 'adds possible values if none selected
end if
set Array1 = f.GetNoValues 'empty array
for i = 0 to pv.count-1 'adds values from the first array
Array1.Add
Array1(i).Text = pv.item(i).Text
Array1(i).IsNumeric = false 'if text in your field
next
'Creates a path and a filename of the output xls-file in the same folder as the current document
