I've just discovered that when Org results are returned in a table, they are modified in that leading 0s are removed. Is this a feature? A bug? Is there a workaround for this? Leading 0s are not removed if the result is a string, but in many cases a string of numbers is still a string and should retain those 0s.
-k.
#+BEGIN_SRC sh :results table
echo "0042"
#+END_SRC
#+RESULTS:
| 42 |
#+BEGIN_SRC sh :results table
echo "00foo"
#+END_SRC
#+RESULTS:
| 00foo |

Maybe you can use a format specifier for that column, so the
zero-padding is retained?

Maybe. Can you provide an example? Adding a #+TBLFM: after the table doesn't do it, and I'm not sure how to specify result formatting at this level of detail in babel header block arguments.
-k.
#+BEGIN_SRC sh :results table
echo "0042"
#+END_SRC
#+RESULTS:
| 42 |
#+TBLFM: @1=@1;N

Take your choice. The feature/bug happens deep down:
- org-babel-execute-src-block
- org-babel-execute:shell
- org-babel-import-elisp-from-file
- org-babel-string-read
- org-babel-read
which tries hard to convert strings to numbers.
I haven't looked hard at this, but it seems like it would take a
significant amount of tooling to set things up to make this
conversion optional.

Lots of ways, I guess. But they would all involve either tricking
org-babel-read and then cleaning up the mess or processing the output
outside of org-babel-import-from-elisp.
For the latter, send the output to a file. Maybe use :file or pipe it from
your script. Then visit the file, convert it to a table, and capture the
result as a string. I think you can do this with a :post callout.
HTH,

I'm now capturing results to :file. This also make the code less dependent on Org. I still manage all the code in Org Babel blocks, but for the following block, which takes several hours to run, I cut-and-paste the code to a terminal. I can do that now that its input is from a file and not from an Org RESULTS block.
-k.
