Is Document Template can be used for creating a Excel File?

I want to create Excel document with some data (i.e. Entity and from associated entities) to Excel Workbook sheet, also I want to capture other entity data in to the same file in a different sheet of same workbook. Is this possible with Document Template? If Yes, can I use the same template(fill data) to import the data into database? First i want to know whether can It be achieved or not? Thanks in advance...

The FileDocument must be created prior to the generation activity. Either a FileDocument object or a specialized entity. The available document types are: 1. PDF 5. HTML 6. WORD 2003 7. WORD 2007 8. ODT 9. RTF

Is it used for only generation of the above documents?
