This is going to be a learning experience for you, but it isn't that hard.
First things first: To open a file, you have to know the COM (component object model) structure for the application. The help files in the app itself will tell you that.
Second, opening Excel or Word from Access involves the creation of an Object variable (note caps because it is specifically a variable of type Object). The code involves
Set myObject = CreateObject("Word.Application")
(or, of course, Excel.Application...)
Now you can open a document. The way you do it depends on the app.
For word:
myObject.Documents.Open
Look up the .Open for Word in the Word Help files for objects.
For excel:
myObject.Workbooks.Open
Again, look up the .Open for Excel in the Excel Help files for objects.
The thing you do next depends on the app, and you weren't specific, so I won't be either.
Don't forget when exiting your code to do a myObject.Close. If you created a new file, precede that with a myObject.SaveAs so you won't lose your work. Look up both methods in the appropriate help files for the specific apps.
For what it is worth, I use this ability all of the time for data import and even sometimes for export. Works great once you get used to it.
But I would never have thought I could EVER get used to anything done inside a Bill Gates product.
