That’s the general rule of thumb when it comes to data. If you throw crap data into a database, all you’ll get out is crap. Unless you’re a wizard, or fairy, of course, which is what I think the company I work for thinks I am. I’ve just been tasked with the fun job of taking two sources of data, and making them “match” for some marketting campaign. One sheet is formatted kinda okay, while the other is hellish to say the least. It doesn’t even have headers for the columns, so I’m going to have to guess my way around this… sighs
