Many languages import tabular contents into elisp tables which are then
inserted into Org-mode buffers as Org-formatted tables.  This should be
possible by replacing the call to `buffer-string' at the end of the
`org-babel-execute:ledger' function with something analogous to the
following (copied from ob-sqlite.el).

--8<---------------cut here---------------start------------->8---
(if (or (member "scalar" result-params)
	      (member "html" result-params)
	      (member "code" result-params)
	      (equal (point-min) (point-max)))
	  (buffer-string)
	(org-table-convert-region (point-min) (point-max))
	(org-babel-sqlite-table-or-scalar
	 (org-babel-sqlite-offset-colnames
	  (org-table-to-lisp) headers-p)))
--8<---------------cut here---------------end--------------->8---

I would recommend this approach over shell-script post-processing.
