Confusing. Anyway:
ConnectionStrings.com - Forgot that connection string? You will find it right here! - get a conn str for your excel file, read it with the MS Access DB Driver
Read into a weakly typed datatable
Transfer into another strongly typed datatable you made, linked with the database. FOllow the instructions in the DW2 link in my signature, section Creating a Simple Data App for more info
No need to d/l from the db because you already have all the info in the strongly typed datatable
Write the datatable to a file
