How to parse JSON strings with embedded JSON strings

Many times I have to deal with JSON documents in which the values are still more embedded JSON documents. For example, from Kubernetes operator framework registry:

{
  "csvName": "etcdoperator.v0.9.2",
  "csvJson": "{\"apiVersion\":\"operators.coreos.com/v1alpha1\",...}"
  "object": [
    "{\"apiVersion\":\"apiextensions.k8s.io/v1beta1\",...}",
    "{\"apiVersion\":\"apiextensions.k8s.io/v1beta1\",...}",
    "{\"apiVersion\":\"operators.coreos.com/v1alpha1\",...}",
    "{\"apiVersion\":\"apiextensions.k8s.io/v1beta1\",...}"
  ]
}

Where the values for "csvJson" and the "object" array are large JSON encoded blobs. I would rather view this as “exploded” JSON:

{
  "csvJson": {
    "kind": "ClusterServiceVersion",
    "spec": {
      "replaces": "etcdoperator.v0.9.0",
      "displayName": "etcd",
      ...
    },
  },
  "object": [
    {
      "kind": "CustomResourceDefinition",
      "spec": {
        "scope": "Namespaced",
        ...
      },
    },
    {
      "kind": "CustomResourceDefinition",
      "spec": {
        "scope": "Namespaced",
        "version": "v1beta2",
        ...
      }
    },
    ...
  ]
}

Here is a short python program to print this format:

import sys,json
def obj_hook(dd):
  for k,v in dd.iteritems():
    if isinstance(v,basestring) and (v.startswith("{") or v.startswith("[")):
      v = json.loads(v, object_hook=obj_hook)
      dd[k] = v
    elif isinstance(v,list):
      for ii, v1 in enumerate(v):
        if isinstance(v1,basestring) and (v1.startswith("{") or v1.startswith("[")):
          v1 = json.loads(v1, object_hook=obj_hook)
          v[ii] = v1
  return dd
print json.dumps(json.load(sys.stdin, object_hook=obj_hook), indent=2)

This assumes you are feeding the JSON document from stdin.
