It goes without saying that the better solution would be to fix the broken data at the source. But if you can’t do that, you could try and fix the problem with a simple regex. Simple, as in “will fail if you throw anything more complicated at it”, but likely sufficient as a quick and dirty solution:

import re
import json
with open("almost.json") as infile:
    jstring = infile.read()
data = json.loads(re.sub(r"(w+):", r'"1":', jstring))

The json standard needs the key with "", so you can’t decode data with json module.
However, you can do it with demjson (pip install demjson).

demjson.decode(data)

Your variables should be like “address” or “city”.

{
  "address":[
    "test1"
  ],
  "city":"test2",
  "country":"test3",
  "postal_code":"test4",
  "state":"test5"
}

You can use json5. JSON5 extends the JSON data interchange format to make it slightly more usable.

import json5
JsonStr = """{
  address:[
    "test1"
  ],
  city:"test2",
  country:"test3",
  postal_code:"test4",
  state:"test5"
}"""

json5.loads(JsonStr)

out:

{'address': ['test1'],
 'city': 'test2',
 'country': 'test3',
 'postal_code': 'test4',
 'state': 'test5'}

”””’

{
  "address":[
  "test1"
  ],
"city":"test2",
"country":"test3",
"postal_code":"test4",
"state":"test5"

}

””

Please change your code format to this , it will works
