Copilot, instead, went on a tear, making things up as it went. It cited “missing values, incorrect labels, inconsistent formats, and duplicate records” — things I had never told it had happened (and didn’t). It cited nonexistent problems such as “many rows with missing values for important variables such as customer ID, purchase date, and product category…, incorrect labels for some variables, such as gender. Some values were labeled as M or F, while others were labeled as Male or Female.”
Not a single piece of information it gave was correct.
It complained that information such as product prices was outdated — untrue. It wrote that “I have attached a spreadsheet with some examples of the data errors I have found, along with the sources and dates of the data.” No such spreadsheet existed. I had no examples of data errors, and no sources and dates for the non-existent data.
