json: How to describe array of array of int

[yashi]

[[1, 2, 3],
 [10, 20, 30]]

How can I describe the data above in data/json.h? I'd like to know both conversion.

• string -> struct
• struct -> string

Hi yashi,

Have you taken a look at JSON_OBJ_DESCR_ARRAY_ARRAY ?

[yashi]

Yes, I did. The macro is actually array of array of objects as you can see from test_json_decoding_array_array(). IOW,

[
	[{
		"height": 168,
		"name": "Simón Bolívar"
	}],
	[{
		"height": 173,
		"name": "Pelé"
	}],
	[{
		"height": 195,
		"name": "Usain Bolt"
	}]
]

Do you have any idea how to replace the objects with integer primitive?
