We have had a number of client requests to read the cell values from cells that contain the Excel database functions:
DAVERAGE, DCOUNT, DCOUNTA, DGET, DMAX, DMIN, DPRODUCT, DSTDEV, DSTDEVP, DSUM, DVAR, DVARP

Currently the all the database functions are unsupported and return the value #NAME if read with the Excel document component.
