Delete info from a JSON using Python -


i exporting database firebase json , want upload bigquery. however, of fieldnames in database have nested information , bigquery not accept way. how can delete 'peripherals' every dataset present in in json. not present in every dataset though. provided example of json code looks below. help!

   {"appname": "dataworks", "foundedperipheralcount": 1, "version": "1.6.1(8056)", "devicetype": "iphone 6", "createdat": "2017-04-05t07:05:30.408z", "updatedat": "2017-04-05t07:08:49.569z", "peripherals": {"1ca726ed-32b1-43b4-9071-b58bbace20a8": "arduino"}, "connectedperipheralcount": 1, "iosversion": "10.2.1"} {"objectid": "20h5hg2inb", "foundedperipheralcount": 0, "devicevendorid": "5b7f085e-b3b6-4270-97dc-f42903cdeac1", "version": "1.3.5(5801)", "devicetype": "iphone 6", "createdat": "2015-11-10t06:16:45.459z", "updatedat": "2015-11-10t06:16:45.459z", "connectedperipheralcount": 0, "iosversion": "9.1"} {"appname": "dataworks", "foundedperipheralcount": 2, "version": "1.6.2(8069)", "devicetype": "iphone 6s", "createdat": "2017-04-12t10:05:05.937z", "updatedat": "2017-07-06t07:33:02.006z", "peripherals": {"060ebafd-3120-4aad-8b0a-ec14a323fa25": "28902               ", "identifierinternalsensors": "internal sensors", "0521a273-faa5-462e-b9ec-fbb3d60f5e99": "28895               "}, "connectedperipheralcount": 8, "iosversion": "10.2.1"}

i have tried 

import json open('firetobq_peripheral.json') out_file:     out = json.load(out_file)     element in out:       del element['peripherals']  print(out)

but receive error 

traceback (most recent call last):   file "editjson.py", line 3, in <module>     out = json.load(out_file)   file "/system/library/frameworks/python.framework/versions/2.7/lib/python2.7/json/__init__.py", line 290, in load     **kw)   file "/system/library/frameworks/python.framework/versions/2.7/lib/python2.7/json/__init__.py", line 338, in loads     return _default_decoder.decode(s)   file "/system/library/frameworks/python.framework/versions/2.7/lib/python2.7/json/decoder.py", line 369, in decode     raise valueerror(errmsg("extra data", s, end, len(s))) valueerror: data: line 2 column 1 - line 629 column 1 (char 311 - 203056)

it looks data in 'firetobq_peripheral.json' not valid json. if each row on new line can use code: 

with open('firetobq_peripheral.json', 'r') in_file:     dicts = []     line in in_file.readlines() :          d = json.loads(line.strip())         if d.get('peripherals'):              del d['peripherals']         dicts += [d]  open('firetobq_peripheral.json', 'w') out_file:     out_file.write('[\n')     i,v in enumerate(dicts):         out_file.write(json.dumps(v)+('\n' if == len(dicts)-1 else ',\n'))     out_file.write(']')

use code formatted json data: 

with open('firetobq_peripheral.json', 'r') in_file:     dicts = json.load(in_file)     d in dicts:          if d.get('peripherals'):              del d['peripherals']  open('firetobq_peripheral.json', 'w') out_file:     out_file.write(json.dumps(dicts, indent=2))
