Loading a json file using python resulting in an error - json

Question

Goof mourning,
When I am trying to load a json file into a mongodb, I am getting the following error:
raise ValueError("No JSON object could be decoded").
In my opinion, my problem come from my second field, but I do not know how to make change "" into a name, or delete it before to load it.
My json file is :
{
"_id" : "585a9ecec62747d1e19497a5",
"" : NumberInt(0),
"VendorID" : NumberInt(2),
"lpep_pickup_datetime" : "2015-11-01 00:57:34",
"Lpep_dropoff_datetime" : "2015-11-01 23:57:45",
"Store_and_fwd_flag" : "N",
"RateCodeID" : NumberInt(5),
"Pickup_longitude" : -73.9550857544,
"Pickup_latitude" : 40.6637229919,
"Dropoff_longitude" : -73.958984375,
"Dropoff_latitude" : 40.6634483337,
"Passenger_count" : NumberInt(1),
"Trip_distance" : 0.09,
"Fare_amount" : 15.0,
"Extra" : 0.0,
"MTA_tax" : 0.0,
"Tip_amount" : 0.0,
"Tolls_amount" : 0.0,
"Ehail_fee" : "",
"improvement_surcharge" : 0.0,
"Total_amount" : 15.0,
"Payment_type" : NumberInt(2),
"Trip_type" : NumberInt(2),
"x" : -8232642.48775,
"y" : 4962866.701,
"valid_longitude" : NumberInt(1),
"valid_latitude" : NumberInt(1),
"valid_coordinates" : NumberInt(2)
}

The problem in your JSON file is not the empty-string key (that is allowed), but the occurrences of NumberInt(...): this is not valid in JSON. You need to provide the number without wrapping it in some kind of function.
So this will be valid:
{
"_id": "585a9ecec62747d1e19497a5",
"": 0,
"VendorID": 2,
"lpep_pickup_datetime": "2015-11-01 00:57:34",
"Lpep_dropoff_datetime": "2015-11-01 23:57:45",
"Store_and_fwd_flag": "N",
"RateCodeID": 5,
"Pickup_longitude": -73.9550857544,
"Pickup_latitude": 40.6637229919,
"Dropoff_longitude": -73.958984375,
"Dropoff_latitude": 40.6634483337,
"Passenger_count": 1,
"Trip_distance": 0.09,
"Fare_amount": 15.0,
"Extra": 0.0,
"MTA_tax": 0.0,
"Tip_amount": 0.0,
"Tolls_amount": 0.0,
"Ehail_fee": "",
"improvement_surcharge": 0.0,
"Total_amount": 15.0,
"Payment_type": 2,
"Trip_type": 2,
"x": -8232642.48775,
"y": 4962866.701,
"valid_longitude": 1,
"valid_latitude": 1,
"valid_coordinates": 2
}
If you have no control over the non-JSON file, then after reading the file contents replace the occurrences of NumberInt like this (in Python):
import re
json = re.sub(r"NumberInt\((\d+)\)", r"\1", json)
