I was sure my custom AI model for sorting client invoices was ready, but a test run with 500 files from our Phoenix branch showed it kept mixing up dates and amounts.

I had to go back and add a whole new layer of checks just for number formats, which took three days, but now it works perfectly. Has anyone else run into this kind of data formatting wall with a project you thought was done?

That feeling of being "done" is the worst trap (been there so many times). Honestly, the data formatting stuff never really ends, it just changes shape. Like, you fix the Phoenix dates, then the London files come in with the day and month swapped. Or a client starts using commas for decimals. It's less of a wall and more of a long, annoying maze you're always in.

Ugh, data formatting is the absolute worst part of any project. It looks done until you hit that one weird batch of files from a different office or system. I swear, cleaning and checking the data always takes twice as long as building the actual model. You fix one thing and another style pops up. It feels like a never ending chore.

I remember a project where 80% of the Phoenix office dates were wrong, just like @bennett.nora said. It's the hidden tax on every single analysis.
