how to get excel report output without pressing preview button or can i run report with pl/sql while print to file options selected

Hi,

i have report layout with excel template and it is working fine manualy. 

Unfortunately i can get excel output only pressing preview button on print dialog. 

my question is is it posible to get excel file directly with menu item plsql code

i have created a code and it is running report but file creating in archive.
