[support] CSV output from Drupal

I am successfully creating a page that creates an Excel spreadsheet. Unfortunately, there are two footer blocks (Devel) that are getting added to the data before Excel opens it. Any ideas how to stop that? I did already add the URL to the block visibility settings to not show it on that page, but it's still there.   Nancy Injustice anywhere is a threat to justice everywhere. -- Dr. Martin L. King, Jr.
