Transforming table and then exporting as CSV

[Pankaj Jangid]

I have the following requirement. For this I have written the code that
follows.

Bank requires from me a CSV file in this format:

--8<---------------cut here---------------start------------->8---
ACCOUNT NO,DR/CR,AMOUNT,NARRATION
50.......658,C,xxxxx.xx,APR2021
50.......590,C,xxxxx.xx,APR2021
50.......904,C,xxxxx.xx,APR2021
06.......965,C,xxxxx.xx,APR2021
50.......489,C,xxxxx.xx,APR2021
50.......680,C,xxxxx.xx,APR2021
50.......357,C,xxxxx.xx,APR2021
--8<---------------cut here---------------end--------------->8---

But this doesn’t have names of the people. First column shows the
account numbers. So I have created an org-table like this

--8<---------------cut here---------------start------------->8---
* April 2021
  :PROPERTIES:
  :TABLE_EXPORT_FILE: enet_apr_2021/0684SAL2904.001.csv
  :TABLE_EXPORT_FORMAT: orgtbl-to-csv
  :END:
  #+NAME: APR2021
  | NAME                  |     ACCOUNT NO | DR/CR |    AMOUNT | NARRATION |
  |-----------------------+----------------+-------+-----------+-----------|
  | Dh........ma...arwal  | 50.........658 | C     |  xxxxx.xx | APR2021   |
  | Pr........ar          | 50.........590 | C     |  xxxxx.xx | APR2021   |
  | Ol........y           | 50.........904 | C     |  xxxxx.xx | APR2021   |
  | Sa........gid         | 06.........965 | C     |  xxxxx.xx | APR2021   |
  | Pa........gid         | 50.........489 | C     |  xxxxx.xx | APR2021   |
  | Ma........ar          | 50.........680 | C     |  xxxxx.xx | APR2021   |
  | Sh........agi         | 50.........357 | C     |  xxxxx.xx | APR2021   |
  |-----------------------+----------------+-------+-----------+-----------|
  | TOTAL                 |                |       | xxxxxx.xx |           |
  #+TBLFM: $4=$4;%.2f
--8<---------------cut here---------------end--------------->8---

I have written below code for the conversion. This code removes the
first column and last row. And then run ‘org-table-export‘. This works
fine.

#+begin_src elisp
(require 'org)

(defun enet-export (name)
  (interactive "MTable Name: ")
  (outline-show-all)
  (let ((case-fold-search t))
    (goto-char (point-min))
    (if (search-forward-regexp (concat "#\\+NAME: +" name) nil t)
        (progn
          (forward-line)
          (let* ((beg (org-table-begin))
                 (end (org-table-end))
                 (txt (buffer-substring-no-properties beg end))
                 (file (org-entry-get (point) "TABLE_EXPORT_FILE"))
                 (format (org-entry-get (point) "TABLE_EXPORT_FORMAT")))
            (with-temp-buffer
              (insert txt)
              (goto-char (point-min))
              (org-table-next-field)
              (org-table-delete-column)
              (goto-char (org-table-end))
              (backward-char)
              (org-table-kill-row)
              (org-table-kill-row)
              (org-entry-put (point) "TABLE_EXPORT_FILE" file)
              (org-entry-put (point) "TABLE_EXPORT_FORMAT" format)
              (make-directory (file-name-directory file) t)
              (org-table-export))))
      (message "Not Found"))))
#+end_src

Same org file has multiple tables, so I am asking for “Table Name”. I
want to do two improvements:

1. When asking for table name, I want to offer all the table names in
   the file as completion options.

2. Current table at point as default

3. I want to run the function from command line. Like,

--8<---------------cut here---------------start------------->8---
   emacs --batch enet_2021_22.org -l enet.el --eval="(enet-export \"APR2021\")"
--8<---------------cut here---------------end--------------->8---

   Do I need to change the (interactive...) part in any way to enable
   this?
