I work Heavily with SQL Server Reporting Services(SSRS), and the relaying of DATA to an excel sheet is done for you; if it is just the DB Data you want to relay. So if your client just wants the DATA with some conditional data amended to the excel sheet look to utilizing SSRS.
To Note SSRS is a paid for service by MSFT. In SSRS you can add excel type logic to the results from the data.
