Bringing up the real issues.

Reverse engineering and game engine/format dissection is my jam. Thanks for sharing.

This would be easiest in either a .Net language (C# probably the easiest), considering you'll want to do a UI. C# and WinForms are easy to get up and running, and you can make mobile UIs easily using whatever .Net web stack you fancy. I'm not sure if there's any native Excel sheet functionality, I don't think so, but surely there'll be a nice library for it handy.

I'm glad to find some justification for all the double-checking and beautification I try to put in before I upload a session's worth of work to github. I mostly do oddball game related projects and emulators, but I've already (very surprisingly) had numerous people email me directly asking me questions about my code and how to use it. If these few people are emailing me, imagine all the people who are finding and copying this code and not bothering to contact me! Every since I've realized that other people are actually interested in some of the code I've made, I try to put my best foot forward.

None of the stuff I'm doing is important in the least, but if I can help any future people who find and are interested in my code, so much the better. This is especially true considering at least one of those people is sure to be myself.
