Sounds like my coworker telling a marketing campaign operator he has yet again let Excel interpret phone numbers as integers. And that he should learn to properly wield Excel. The downstream system is a call center made of humans. They lose a few seconds inputting the phone number manually though. No lead is lost. I don't want to speculate too much, but I think we might be in the clear. The client is not losing too much money. But if he complains once, we'll have to implement more checks to validate the Excel file. Then I'll have to buy my coworker breakfast, so that he doesn't bitch the whole implementation time. Such is life.
