Ah, reminds me of something I had to do only two years ago. Business side would send an excel file with thousands of lines and some columns with some definitions. These we would export to csv and turn into a huge enum using some generator. One definition per line in the excel document, on the form Rule67_Oslo(245, 167, NO_TRANSFER). One day it failed, as the byte count was too big. Managed to strip down the definitions some, but a few weeks later it was impossible to add new rules again. No idea why someone would make that design in the first place, old legacy system. But it was hard to refactor as well, as those constants were littered everywhere in the code as well. I switched teams before it was solved, but I think the fix was mainly that business had to find one rule to remove every time they wanted to add a new one..
