What Data are you trying to export?
When a report is run, at the top of the screen in the report viewer there is a print icon should you wish to print, or if you click the floppy disc icon, you can export to Excel or PDF.
Hope that answers your question, otherwise do come back with more information so I can help further.
Sorry, can you be a bit more specific on what data you are trying to get? What are you trying to achieve?
This will help me to talk you through what steps to take
