How do you export to an OpenOffice Calc spreadsheet?
From Frank Strunzkus:
This example goes through a notes view and exports some fields of each notes document into a table row in openoffice calc.
You can choose if the user should be able or not to see the OpenOffice application while the export agent is running. Once the OO file is ready it will be saved to harddisk.
My example requires a oo calc file that will be used as a template. This template will be filled with data comming from notes. (Google for examples, if you prefer to create a empty file rather than using a preformatted one like I prefer.)
To test my demo you first need to create the template file on your C: drive. Create a simple empty .ods file. My example requires that there is a at least one table in the file that has the name "Sheet1".

'E.g. pass the Hidden=True property to the app object to run the application in the background
'If you do not have to set properties, you do not mandatory need this class in your code
