With Microsoft Excel, you can create custom functions using Visual Basic for Applications. You can also use Data Access Objects (DAO) to programmatically return information from an external database. This article includes sample macro code that uses DAO to return an array of data to a custom worksheet function.
The following sample macro assumes you have installed the Data Access Objects component of Microsoft Office and the Northwind database files (Customer.dbf, Employee.dbf, and Orders.dbf) on your computer.
NOTE: By default, the Northwind database files are installed in the Program Files\Microsoft Office\Office\1033 folder.

This article assumes that you are familiar with the programming language being demonstrated and the tools used to create and debug procedures. Microsoft support professionals can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific needs.

(http://support.microsoft.com/default.aspx?scid=fh;EN-US;CNTACTMS)To use the example macro, follow these steps:
NOTE: If the function returns more data than the range of cells can contain, the data is cut off; that is, the range does not expand to hold the returned data. If the range of cells is too large, cells that do not contain any data display the #N/A error value.
