I usually start by trying to keep the external interface as small as possible. 
So, from a shell you would do

 gnudoit '(untabify-file "c:/path/to/filename.x")

or

 emacsclient -e '(untabify-file "c:/path/to/filename.x")

(I use Cygwin's bash shell; adjust the quoting if you use Windows CMD shell).

This means you need to write the untabify-file function in emacs and load it
before calling it from gnudoit/emacsclient :

(defun untabify-file (filename)
  "Load the file FILENAME and untabify and save it."
  (interactive "f")
  (save-excursion
    (let* ((buffer (get-file-buffer filename)) ;; see if file is already loaded
           (file (or buffer (find-file-noselect filename))))
       (set-buffer file)
       (untabify (point-min) (point-max))
       (and (buffer-modified-p)
          (save-buffer))
       ; if file was not already loaded, kill it
       (or buffer (kill-buffer file)))))
