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'. Regards, -- Nicolas Goaziou
