When you load a column with these data types into the Power BI model, a Date/Time/Timezone column converts into a Date/time data type, and a Duration column converts into a Decimal number data type. I looked it up and tried the following : If it is showing error that It cannot be converted, obviously there are some garbage value in the column like - space, string or other values not a number. And we can do that with either ADDCOLUMNS or GENERATE/ROW construct, The below image show the result of the JoinStringAndNumberSeries variable.
