Note that the Windows binaries already contain xlwt and xlrd. Jürgen was
so kind to include it, because I needed it as well for my plugins. Not
sure about openpyxl. On Linux systems it is rather easy to install them
through apt-get, pip or similar mechanisms. Just tell your users
that/how they need/can install them.

Hi!
We are currently developing a QGIS plugin were we wish to generate
some Excel files as output.
In order to build the spreadsheet file we need to use some python
modules installed from pip (openpyxl, xlwt, etc). This dependency
will force every user to manually install the needed package form
the pip repository.
This situation leaves us with the following question: is possible
or it will be in the future to manage this kind of dependencies from
QGIS side when the user installs the plugin?
Although it has been discussed and some prototyping was done to
support automatic installation of dependencies at the last hackfest,
there isn’t anything in the released versions of QGIS to support this
yet. If your packages have no operating system specific binaries in
them, then I suggest to bundle them into your plugin and use an
appropriate import path relative to your code. Note there is a limit
on how big your plugin can be (I think it is 10mb) so you need to
ensure your 3rd party deps do not bulk out your plugin too much.
We bundled xlwt and xlrd as .egg with a plugin recently:
https://github.com/opengisch/shpsync/blob/master/xlwt-1.0.0-py2.7.egg
https://github.com/opengisch/shpsync/blob/master/xlrd-0.9.4-py2.7.egg
Until there's a cross-platform dependency management (which I know
that several people are looking into) that's the safest road to follow.
Best
Matthias
