Add value from Excel into grouped list

Good morning
I need to add value from Excel into a grouped list of revit.
In excel I have some values ​​concerning a series of “Rooms” of the same type.

How can I solve the problem?
Thanks

Element.SetParameterByName.

i believe you have 17 nested list in your element right? you can either duplicate the values and make it into the same list structure as your element, or try set the lacing of setparameterbyname to longest

As @JacobSmall said Element.SetParameterByName. Take the Element @L2 and value @L1 if it doesnt work by default.

Make sure you have the same amount of Lists (17) as values (17)
