try something like:

#+begin_src emacs-lisp 
  (mapconcat
   'identity
   (append
    '("row0datastring" "row0datastring" "row0datastring")
    '("row1datastring" "row1datastring" "row1datastring")) ",")
#+end_src

#+results:
: 
row0datastring,row0datastring,row0datastring,row1datastring,row1datastring,row1datastring
