Need to quickly export some data to Excel? How about doing it in just a couple of lines of code?

Excel Export Plugin is a Rails plugin to do just that.

Install the plugin:
ruby script/plugin install http://svn.napcsweb.com/public/excel

Here is an example method:

def export_project_to_excel
  e = Excel::Workbook.new
  @project = Project.find(:all)
  e.addWorksheetFromActiveRecord "Project", "project", @project
  headers['Content-Type'] = "application/vnd.ms-excel"
  render_text(e.build)
end
