Some strings get imported as numbers

[latifs]

Hey guys,
Trying to import a collection from a JSON file that happens to be in this format:

{
    "manufacturer": "hello",
    "name": "world",
    "grading": "8",
    "status": "completed",
    "submitted_on": "{\"type\":\"timestamp\",\"data\":\"10/4/18\"}",
    "submitted_by": "fox mulder",
    "approved_for": [
      "group-2",
      "group-3",
      "group-4"
    ]
  },

For some reasons grading gets imported as a number.
Am I Missing something?

Thanks
