How to correctly mock a multiple level depth object in JSON

#1

For JSON object like below
{a:{b,c:{d:e},f:{g:h,i:j}}}
How to correctly add them to the row like template in the website instead.
I learn that for 1 layer you can do it like a.b
but what about e , do I have to type a.c.d or just c.d will do ?
