The thing is to connect the right information to the right object.
You’ll have to think of a way to do that, because they all look sort of the same in a list.
I use the objects Id or UniqueId to make sense of what i’m doing before it get’s chaotic.
If you can find another unique combination of the values in the fields in excel and in the schedule that separates out every individual object, there might be an other (complex) way.
