Package Validation Error in SSIS - Unicode and Non Unicode conversion error

Hi,

I am trying to transform sql table data to excel file using SSIS. But it gives me package validation error.

I googled this problem but as a solution many persons has written “convert between unicode and non-unicode string data types”. In the sql table all columns are varchar type so how we can they that data is Unicode. Unicode data always resides in nvarchar data type.

Below is the actual problem which I am facing. I am new to SSIS so kindly give the described solution.
