Using Excel as an I/O for a Fortran program

I have a medium sized Fortran 77 program that I want to run on a windows PC using Absoft Pro Fortran. I want to generate the input file on Excel and read the output file and do plots on Excel. Has anyone done this type of work? I would like to obtain a sanitized copy of a program that can do this. ## Deliverables Complete and fully-functional working program(s) in executable form as well as complete source code of all work done.
