Another way to do it is to control MS Word via ActiveX. You just have to open the document, read data from all included tables and do the calculations. You have some examples on haw to use ActiveX in Labview folder\examples\comm\. Also, you can find everything about needed methods and properties in VBA Help included in MS Word. Also, if those docs contain just tables, you can save them as text files (each cell will be a text row).
Good luck!
