Depends.  Are you creating the reports programmatically or through some generic query?  Programmatically, you can parse the output into Spreadsheet XML (Excel 2003) which can be opened directly with Excel and can include column widths and cell formats.

Will this require a new Serenji license for the debugger or will the existing one work?  

Ok.  Thank you.
