the cronospro format sounds painful. did you consider asking the vendor for the spec, or was the reverse engineering half the fun?

CronosPro is a proprietary format and it is assumed you are using their own software to manipulate it. As it is closed source and not really a software we dare to run on managed devices, exporting data from the Cronos format to CSV through the proprietary software becomes quite a hassle. And this is the reasoning behind the whole reverse engineering.

But of course it was a fun process and very satisfying when the normalizer actually started to work.
