This ist basically my daily work. I have to write Java code in excel files which then are being converted into a DSL and then again being converted into Java code. On top of that many wrappers were built which abstract all this things away..

We have about 30 such excel files which contain about 50000 business rules.
There is no version control for this tables and 5 different team are working on the same tables parallel.

The name of this framework is Drools or as I call it: HELL 😡
