Trusted data providers are external databases that Excel Calculation Services is explicitly configured to trust when processing data connections in workbooks. Excel Calculation Services attempts to process a data connection only if the connection is to a trusted data provider.
You can control access to external data by explicitly defining the data providers that are trusted and recording them in the list of trusted data providers. The list of trusted data providers designates specific external data providers to which workbooks opened in Excel Calculation Services are permitted to connect.
Before instantiating a data provider to enable a workbook to connect to an external data source, Excel Calculation Services checks the connection information to determine whether the provider appears on the list of trusted data providers. If the provider is on the list, a connection is attempted; otherwise, the connection request is ignored.
