It is already possible. When asked for a format for conversion, you can
write something like:
orgtbl-to-csv :fmt tvd-org-quote-csv-field
You can also define your own format:
(defun my-orgtbl-to-Excel (table params)
"Convert the orgtbl-mode table to Excel.
This does take care of the proper quoting of fields with comma or quotes."
(orgtbl-to-generic table
(org-combine-plists '(:sep "," :fmt
tvd-org-quote-csv-field)
params)))
and use it when prompted for a format in `org-table-export'.
