heres the code--replace the Initial Catalog (database) in the Connection string.

Add a Reference to the Excel Library.

The Excel file will be saved to the bin/Debug folder.

Instead of a Function-use a Sub. functions must return a value and your code doesn't.

Also set a Reference and Import System.Data.SqlClient.

Replace the Query in the Button_Click event
