Spent 3 hours trying to fix a CSV file for an AI model yesterday

I was trying to feed a big dataset into a custom AI classification tool I found on GitHub. The CSV file had some weird formatting from an old database export. It took me about 3 hours to figure out the line breaks were causing the model to ignore half the rows. I checked everything from column headers to missing tags before I noticed the pattern. Now I'm wondering how often small data cleaning issues mess up people's AI projects. Has anyone else run into a simple data problem that ate up your whole afternoon?

Wait, you're telling me line breaks were the problem? Like the actual line break characters that every text editor hides by default? That's brutal, I would have been pulling my hair out for way longer than three hours before even thinking to check something that basic.

Agree with @coleman.keith here. Three hours is actually pretty fast for something like that. I spent a whole afternoon once trying to figure out why my config file wasn't loading, and it turned out to be a single hidden tab character that broke everything. Those invisible characters are the worst. You just don't think to look for them until you're ready to throw your computer out the window.
