Dictionary Within Array Of Dictionaries - Pulling Out Values

I would like to get data onto my worksheet that looks something like what I have below. I'm pretty set on using Dictionaries to get the data into this format

(row 1 reads): header 1, header 2, header 3
(row 2 reads): value 1, value 2, value 3
(row 3 reads): value 1, value 2, {"property1": property1, "property2": property2, "property3": property3}

I'm close to doing so but having issues with my syntax.

I can refer to:
arrExport(1)("key3") to get the value in key3

but I cannot refer to:
arrExport(1)("key4")

Because key4 is what contains another dictionary.

Code:
Sub DictWithinDict()

Dim dict As dictionary, dictValue As dictionary
Dim arrExport() As dictionary
Dim i As Integer

ReDim arrExport(1 To 10) 'real data will be in thousands
