Hello Ihor,

Many thanks for the insights.  Ok, I guess this it likely to take some
time, but it would be a great feature in my option.

Thanks for the suggestion. I tried using post replacing semi columns by
commas but was surprised by the output.

# file test.csv
# 123;0;123

#+NAME: specific-delim
#+BEGIN_SRC emacs-lisp :var tbl=""
(replace-regexp-in-string ";" "," tbl)
#+end_src

#+RESULTS: specific-delim



#+begin_src awk :in-file test.csv :cmd-line -F ";" :post specific-delim(*this*)
 {print $0}
#+end_src

#+RESULTS:
: 123,0,123



After a short investigation, I notice that the function
org-babel-import-elisp-from-file, is the function making the call wheter
the result should be a table or not i.e before the :post argument. Have
I understood correctly?

If it is the case, then I would have to not just replace the delimeter
but convert the entire results to an org-table.

Best regards,
Jeremie
