What a great question. You've come to the right community.

My main concern would be to make sure there are no passwords or secret keys in the data, not how it looks.

You'll open yourself up for comments. They may be positive or negative. You'll only know how it pans out afterwards.

Is the code something that you'll want to improve on for further research? If so publish it on github. It opens the way for others to contribute and improve the code. Be sure to include a short readme that you welcome PRs for code cleanup, etc. That way you can turn comments criticizing your code into a request for collaboration. It'll really separates helpful people from drive by commenters.
