Internal table data into Excel sheet with header

Hi

I have created a report and i want to down load the data into Excel file.

I have used the function modules like SAP_CONVERT_TO_XLS_FORMAT, MS_EXCEL_OLE_STANDARD_DAT. In my excel sheet I am not getting Header.

After i have used function module XXL_FULL_API.

Is any other function module or BAPI that can import data into excel sheet with header data.

Thanks
