Adding two value to single cell of excel under each other

Dears,
Is it possible while adding two values to single cell of excel bellow each other?
And is it possible to make one of them bold and other standard. See picture bellow:

I believe that two values separated by a carriage return is possible. Insert a carriage return in the string before you write the data to excel.
In a code block try typing:
A+"
"+B;
If that doesn’t work use a string node with just the return in it.

Not sure about the building of the text.

Thanks a lot Jacob. It worked great.
