Nah just stupid number formatting, my UPCs regularly turn into scientific notation or my UOM automatically convert to a string ="12" which ruins math operations so first I have to make a helper column =NUMBERVALUE([@UOM]).

Or being unable to convert datetime to a simple date for date calculations without loading the table into power query and transforming it there. You can change the format into short date but if the actual value is datetime it will still throw an error but now the type issue is hidden, so have fun reading docs and troubleshooting until you realize your mistake :)

You can make a date from a datetime in cell A1 with

=Date(year(A1), month(A1), day(A1))
