This is because quoting the arguments to echo does not work when your
input contains unescaped quote characters.  I've no idea how exactly
babel tries to get it's arguments to the command, but it looks like it
simply copies text and executes the resulting script?  If it could open
a pipe and send the data through, no quoting would be necessary since
the shell never sees the data.  I'm not sure if that's possible because
I can't find specific documentation on language "sh".

[Note: orgmode online manual links to
 http://orgmode.org/worg/org-contrib/babel/languages/ which is broken.]

So, you're using a un*xoid?  This is your lucky day, since in your case you
should be able to use a here script:

#+begin_src sh :var data=excel-from-bank :results output
echo <<EOF | cmd1 | cmd2
$data
EOF
#+end_src


HTH,
Achim.
