Humans also stumble with that as well. Problems being CSV not really being that well defined and it is not clear to people how quoting needs to be done. The training set might not contain enough complex examples (newlines in values?)
Even if you get it to work 100% of the time, it will only be 99.something%. That's just not what it's for I guess. I pushed a few million items through it for classification a while back and the creative ways it found to sometimes screwup, astounded me.
Yeah and that's why I'm skeptical of the idea that AI tools will just replace people, in toto. Someone has to ultimately be responsible for the data, and "the AI said it was true" isn't going to hold up as an excuse. They will minimize and replace certain types of work, though, like generic illustrations.
