This sounds really cool. I have actually made something similar (unpublished and quite hacky though).
I work as a self-employed contractor and must report my times in varying standardised formats, depending on the client or agency I am working with. My input data comes from TimeWarrior (like yours) and I usually just output CSV data so I can copy-paste that into a provided excel template.
Quantizing the data is usually the most essential step as the templates often restrict accuracy. I find it strange that many of the comments here presume this kind of transformation to be fraudulent.
In Germany, the characters are called Petzi (also the name of the book series) and Pingo.
