If you like to export you Xcelsius data to Excel from a runtime dashboard there is a great add-on for the Tomcat application server provied by ClearPeaks www.clearpeaks.com.
This solution named Export2Excel is free and can be downloaded here.

The configuration is quite easy.

1. Download the WAR file
2. Copy the ExportToExcelv2.war into your Tomcat webapps folder
3. Restart Tomcat application server
4. Run Xcelsius
5. Open Data Manager
6. Add XML connection
7. Set the XML Data-URL to http://servername:port/ExportToExcelv2/index.jsp
8. Configure the “Enable Send” funcion, which contains the dataset you like to export to Excel.
9. Be sure that you type URLDummy as the Name of the "Enable Load", and that the Range contains just one cell. This cell is the URL of the exported Excel file.
10. Now you can implement a button to your dashboard, which exports the configured dataset to excel.
11. Last but not least you may add a button to call the URL, where the exported excel file resists.

There is also something similar from Centigon Solutions Inc. called Xport Wizard, which handles more output formats, but is not for free: http://www.centigonsolutions.com/xportwizard/index.html

Maloy Manna a.k.a. biguru has also described on his Blog, how to implement this method on a .NET application server:
