I can see an option in MS word where we can compare two versions of document(legal blackline) May I know is there any way to be achieved through Bot without spying or using macros. Do we have any code or VBO for this?
The standard Word VBO from BP has very limited capability and doesn't have the functionality you're looking for.

Maybe somebody in the Community has already done this and is willing to share, but if not, then I'd recommend as a first step to manually record a macro and then study the resulting code. A quick Google suggests a couple of methods:
