Result Json parsing expands dotted keys (within quotes).

Hi,

When I have a json with keys that have a '.' in them, within quotes, the resulting json has those keys expanded:
`{
    "Settings": {
        "Datasets.Title": "Datasets title"
    }
}`

The result is:
`{
  "Settings": {
    "Datasets": {
      "Title": "Datasets title"
    }
  }
}`

OpenAI leaves the keys as is, the result does not.
