One task that most people are faced with at some point in time is the need to import data into SQL Server from an Excel spreadsheet. These options are great, but they may not necessarily give you as much control as you may need during the import process. With SSIS you can import different types of data as well as apply other logic during the importing process. One problem though that I have faced with importing data from Excel into a SQL Server table is the issue of having to convert data types from Unicode to non-Unicode. SSIS treats data in an Excel file as Unicode, but my database tables are defined as non-Unicode, because I don't have the need to store other code sets and therefore I don't want to waste additional storage space. Is there any simple way to do this in SSIS?

This example will look at the Product tables used in the transaction database AdventureWorks as well as the data warehouse version of the Product dimension table. You can download these databases by going to CodePlex. The staging package is simple.
