I am getting a bit of headache just because a simple looking, easy statement is throwing some errors in my face.

I have a json file called strings.json like this:

"strings": [{"-name": "city", "#text": "City"}, {"-name": "phone", "#text": "Phone"}, ...,

            {"-name": "address", "#text": "Address"}]

I want to read the json file, just that for now. I have these statements which I found out, but it's not working:

import json

from pprint import pprint



with open('strings.json') as json_data:

    d = json.load(json_data)

    json_data.close()

    pprint(d)

The error displayed on the console was this:

Traceback (most recent call last):

File "/home/.../android/values/manipulate_json.py", line 5, in <module>

d = json.loads(json_data)

File "/usr/lib/python2.7/json/__init__.py", line 326, in loads

return _default_decoder.decode(s)

File "/usr/lib/python2.7/json/decoder.py", line 366, in decode

obj, end = self.raw_decode(s, idx=_w(s, 0).end())

TypeError: expected string or buffer

[Finished in 0.1s with exit code 1]

Edited

Changed from json.loads to json.load

and got this:

Traceback (most recent call last):

File "/home/.../android/values/manipulate_json.py", line 5, in <module>

d = json.load(json_data)

File "/usr/lib/python2.7/json/__init__.py", line 278, in load

The json.load() method (without "s" in "load") can read a file directly:

import json



with open('strings.json') as json_data:

    d = json.load(json_data)

    print(d)

You were using the json.loads() method, which is used for string arguments only.

Edit:
The new message is a totally different problem. In that case, there is some invalid json in that file. For that, I would recommend running the file through a json validator.

There are also solutions for fixing json like for example How do I automatically fix an invalid JSON string?.

Here is a copy of code which works fine for me

import json



with open("test.json") as json_file:

    json_data = json.load(json_file)

    print(json_data)

with the data

{

    "a": [1,3,"asdf",true],

    "b": {

        "Hello": "world"

    }

}

you may want to wrap your json.load line with a try catch because invalid JSON will cause a stacktrace error message.

The problem is using with statement:

with open('strings.json') as json_data:

    d = json.load(json_data)

    pprint(d)

The file is going to be implicitly closed already. There is no need to call json_data.close() again.

In python 3, we can use below method.

Read from file and convert to JSON

import json



# Considering "json_list.json" is a json file



with open('json_list.json') as fd:

     json_data = json.load(fd)

or

import json



json_data = json.load(open('json_list.json'))

Using with statement will automatically close the opened file descriptor.

String to JSON

import json



json_data = json.loads('{"name" : "myName", "age":24}')

To add on this, today you are able to use pandas to import json:

You may want to do a careful use of the orient parameter.
