C#: In an object is it possible to convert decimal values to a string or double?

I have a Json object which I get from rest call and there is no specific format. Is it possible to iterate through the object and check if any decimal value exists and convert it to a string/double?

I need to pass this object into a couchbaseLite's MutableDocument which doesn't allow any decimals

Object

{
 "performer": [
    {
      "referedBy": "ABDC",
      "text": "XYZ"
    }
  ],
  "quantity": {
    "value": 100.0, **// --> This should bee converted to "100.0"**
    "system": "http://unitsofmeasure.org",
  },
"range": [
    {
      "low": {
        "value": 0.0, **// --> This should bee converted to "0.0"**
        "system": "http://unitsofmeasure.org",
      },
      "text": "Total values"
    }
  ]
}

I tried to do it by checking the specific properties and fixing it i.e., check for "quantity", "range" etc. But wondering if there is a better way to iterate through the object i.e., a generic method that can iterate through the object that can convert the decimals to integer/double as I won't know the exact format of the object beforehand.

Code:

private static void UpdateQuantity(JToken result)
        {
            var quantity = (result as JToken)["quantity"];
            if (quantity == null)
            {
                return;
            }
            //update value from deciaml to string in quantity
            string quantityValue = null;
            foreach (JToken token in (result as JToken)["quantity"].Children())
            {
                JProperty ps = token as JProperty;
                if (ps != null && ps.Name.Contains("value"))
                {
                    quantityValue = ps.Value.ToString().Replace(',', '.');
                    ps.Replace(new JProperty("value", quantityValue as object));
                    break;
                }
            }
        }

Solution

The following code should work for you

foreach (var token in
    obj.DescendantsAndSelf().OfType<JObject>().SelectMany(o =>
        o.Properties().Where(p => p.Value.Type == JTokenType.Integer || p.Value.Type == JTokenType.Float)))
{
    token.Value = token.Value.ToString();
}

dotnetfiddle

Take all descendants of the root object, including itself.
Which are JObject
Select all their properties where...
... the JSON type of the property value is either Integer or Float
For each one, change the value to be the stringified form of the same value.
