Reading MS Excel 2010 document

Hello Experts, I have a requirement to create a VuGen script which opens an excel file from a shared folder. Reads the content of the file and validates it. 

I am using LR 11.03.

This script is meant to be run by BPM for monitoring purpose. Therefore I cannot use VBScript or VB to launch open the document and read the content as BPM wont render the excel. 

I want to know if there are appropriate MS libraries that I can use in COM/DCOM protocol. Vugen Protocol advisor seemingly did not help.

Appreciate your respones.

Thanks,

Alaksh
