      It would help if we can add an example on how to export sub documents in an array.

      For example, if we have a document like this:

      {
	"_id" : ObjectId("527b09b18c6f25a12b5aadb6"),
	"a" : {
		"b" : [
			{
				"c" : 2
			},
			{
				"c" : 3
			}
		]
	}
}

      To export the first element of array b, use “a.b.0” as the field name:

      mongoexport -d <database> -c <collection> -f "a.b.0"

      To export the value of c in the first element of array b, use “a.b.0.c” as the field name:

      mongoexport -d <database> -c <collection> -f "a.b.0.c"
