Circe-Json retrieve all keys

HI to every one,

I’m using circe, do you know if there any way to retrieve from json object a list with the keys?, for example:

	"key_1": "value_1",
	"key_2": {
		"key_3": "value_3",
		"key_4 ": "value_4"

I would like to retrieve a list with this content: “key_1”,“key_2” , “key_3” , “key_4”

Thank you very much… :slight_smile:

Two examples (without handling arrays) are

For the arrays, you also need a comparable asArray, that only handles values.
