Can't parse json file: json.decoder.JSONDecodeError: Extra data.

Question

I have a json file. A simplified version of it looks as following:

{
  \"host\": \"a.com\",
  \"ip\": \"1.2.2.3\",
  \"port\": 8
}
{
  \"host\":         


        

Answer 1

Your JSON file isn't available in proper format.
It should be like this, inside a list, comma separated:

[
    {
     "host": "a.com",
     "ip": "1.2.2.3",
     "port": 8
    },
    {
     "host": "b.com",
     "ip": "2.5.0.4",
     "port": 3

    },
    {
     "host": "c.com",
     "ip": "9.17.6.7",
     "port": 4
    },
]

Answer 2

As you already found out: that is not valid JSON.
You have to modify it to make it valid, specifically, you have to wrap your top-level objects in an array. Try this:

import json
from pprint import pprint

with open('myfile.json') as f:
    data = json.loads("[" + 
        f.read().replace("}\n{", "},\n{") + 
    "]")

    print(data)

Answer 3

Your JSON data set is not valid , You can merge them into one array of objects. For example :

[
    {
        "host": "a.com",
        "ip": "1.2.2.3",
        "port": 8
    }, {
        "host": "b.com",
        "ip": "2.5.0.4",
        "port": 3

    }, {
        "host": "c.com",
        "ip": "9.17.6.7",
        "port": 4
    }
]

In JSON you can't have multiple objects of top-level but you can have array of objects and it is valid
