Opening and saving Excel with Teamcenter

Hello,
I need to export some data from the NX model in TC to Excel dataset that also is already in Teamcenter (or can be created as a new one or from template, but later needs to be put in the TC automatically)
I have one backup idea if this wasnt possible (asking user to open the Excel manually and then running the journal, the data would be then exported to the active Excel spreadsheet), however I would like it to be simpler, so the user would not have to open the excel file manually. Do you have any ideas how this could be done, if possible?
