Something like this in Emacs lisp?

(defun grind ()
(interactive)
(save-excursion
(beginning-of-defun)
(indent-pp-sexp)))

It probably needs tweeking, may require a late version of Emacs, may not
leave point where you expect. I haven't tested it. Just wondering if
it is the general idea you are looking for.
