We could write a turn key solution, but more than likely it won't include one or two more steps in the scope that you have failed to mention. Moving data from one file to another one isn't a task for newbies, as it requires knowledge of OLE, or some other "CABINET" or "CLASS" of functions.
Post some code on where you are stuck and we can help, otherwise we will have to decline as we cannot provide you with a turn key solution. We have done it before, and thirty revisions later, the end user still says it doesn't do exactly what THEY want (even though we have written all of the code based on all of the specifications given, most users cannot place the correct entries into the correct variables to make our solution bullet proof!)
Sorry, but if you post where you are stuck, we can help!
I have said it once, I will say it again. IT!
