Awesome module! I’ve been playing around with POI recently as well. Do you have this project on github? Or would you be interested in having others collaborate? I was thinking about creating a module very similar to this based on my recent blog post. I was hesitant at first because of the number of dependencies that the POI requires (didn’t want it to conflict with other appstore modules) but then I came across Andrej’s blog post about managing java dependencies that looked very promising.
