Overwrite the data in excel using SSIS

Question

Hi, I have to load data from Sql server to excel daily and have to send that excel via mail. If I run two time the same package , data will be appended into the excel. I dont want to append the data, but want to overwrite If same day. And If run next day It should create a new file with Filename and suffixed by Date like Filename_20160301 for 1st march. How do we achieve this? Could you give by example as i am new to SSIS?

I do not want to use drop and create excel table as I have some limitation. i want to achieve this using script task.

Thanks in advance..
