ssis change datatype from one table to another

Hello guys,

I need some help. I have to tables(table1, table2) in my database.(SQL Server 2005)

Initially i created an ssis Package to import data from excel files to table1. The datatype for each columns are "nVarchar(255)". It works very well.
The table2 has columns with different datatype. such as varchar, decimal(10,2), datetime.

What i want to do?

I want to create a new ssis package to import data from table1 to table2 converting the datatype of  "nvarchar" from table 1 to their respective datatype in table2. can you give some steps of how to do this.

please help. i am new to ssis since 3 weeks only.

thanks vayl1.
