C# and crystal reports

I have C# windows forms application. I am generating Crystal reports through Sql stored procedures. My client wants to ADD/EDit the reports exporting into word documents. I am able to export crystal report ? to word 2007? but not able to edit the word document or add new text and format the reports in word document 1. Bid for converting the crystal reports into word documents that can be edited/[login to view URL] new text. OR 2. Generate reports in Microsoft word 2007 that can be edited/add new text and format as much as user likes it.
