I did not follow the thread, but reading ods files into org is easy, if
you have access to R:

--8<---------------cut here---------------start------------->8---
#+name: firstsheet
#+begin_src R :colnames yes
  library("ROpenOffice")
  read.ods("~/tmp/not.ods")[[1]]
#+end_src

#+results: firstsheet
| first col | second col | third col |
|-----------+------------+-----------|
|         8 |          4 |         5 |
|      1541 |         79 |       628 |


#+name: secondsheet
#+begin_src R :colnames yes
  library("ROpenOffice")
  read.ods("~/tmp/not.ods")[[2]]
#+end_src

#+results: secondsheet
| dtr   | egd   | pdrn |
|-------+-------+------|
| ugn   | apggh | gpd  |
| ulgnd | pugn  | pdsg |
--8<---------------cut here---------------end--------------->8---
