Data migration Memes

Database normalization? Foreign keys? Proper schema design? Never heard of her. When it's time to migrate that legacy database that's been held together with duct tape and prayers, you'll find yourself begging the data to just... be normal . But nope, Excel decides to show up to the party uninvited, screaming its head off with its CSV exports, date formatting nightmares, and those delightful cells that randomly convert everything to scientific notation. The real horror? When stakeholders hand you a 47-tab Excel workbook with merged cells, inconsistent data types, and formulas that reference other workbooks on someone's laptop from 2014. "Just import this into the new system," they say. Sure, right after I finish my therapy sessions.
