Sentihood Dataset is a dataset for Target Aspect-based Sentiment Analysis. Its Test and Train file are available in Json format. However, when I try loading it using the json module of python, it gives the following error-
JSONDecodeError: Expecting value: line 7 column 1 (char 6)
Is there some other way of loading Json files? I don't have much knowledge of Json and hence would appreciate any help.

My code is simply:
with open("sentihood-train.json", "r") as read_it:
data = json.load(read_it)
When file is reading json.loads needs file content which can be done by following way. Pass f.read() in json.loads line.
import json
with open("test.json",mode='r') as f:
d = json.loads(f.read()) # changed this line
print(d)

The google colab code is shown below:
annotations = []
with open('/content/orig.json') as f:
for line in f:
annotations.append(json.loads(line))
The error which I get is
JSONDecodeError: Expecting property name enclosed in double quotes: line 2 column 1 (char 2)
Let me know if I need anymore details.
Assume that your file is .json extension but every line is a JSON string, then line 2 in your JSON file 'orig.json' is malformed, it's not in correct JSON syntax, eg. JSON needs doublequotes around keys (properties) and values, not singlequotes.
But normally, when your files come with .json extension, you don't read line by line that way, parse the whole file instead:
annotations = []
with open('/content/orig.json') as f:
text = f.read()
annotations.append(json.loads(text))
I am using Python to convert data from a xml file to json and putting it in a file. I am using xmltodict to convert to dictionary using 'parse' and then converting into json using 'dumps'. Here is the code below: -
import xmltodict
import json
with open('note.xml') as xml_file:
my_dict=xmltodict.parse(xml_file.read())
xml_file.close()
json_data=json.dumps(my_dict)
with open('note.json', 'w') as f:
json.dump(json_data, f)
Here is a sample xml file that I have used. However, in the output, I am getting something not quite json like, with the added backslash. Looks like gibberish: -
"{\"note\": {\"to\": \"Tove\", \"from\": \"Jani\", \"heading\": \"Reminder\", \"body\": \"Don't forget me this weekend!\"}}"
I am trying to understand why I am not able to get data in proper json form. Is there anything wrong with my code? Please note that I am not a very skilled programmer and have only used Python sporadically.
You need to add below code after json_data=json.dumps(my_dict) to convert string to json object
json_data = json.loads(json_data)
I have big size of json file to parse with python, however it's incomplete (i.e., missing parentheses in the end). The json file consist of one big json object which contains json objects inside. All json object in outer json object is complete, just finishing parenthese are missing.
for example, its structure is like this.
{bigger_json_head:value, another_key:[{small_complete_json1},{small_complete_json2}, ...,{small_complete_json_n},
So final "]}" are missing. however, each small json forms a single row so when I tried to print each line of the json file I have, I get each json object as a single string.
so I've tried to use:
with open("file.json","r",encoding="UTF-8") as f:
for line in f.readlines()
line_arr.append(line)
I expected to have a list with line of json object as its element
and then I tried below after the process:
for json_line in line_arr:
try:
json_str = json.loads(json_line)
print(json_str)
except json.decoder.JSONDecodeError:
continue
I expected from this code block, except first and last string, this code would print json string to console. However, it printed nothing and just got decode error.
Is there anyone who solved similar problem? please help. Thank you
If the faulty json file only miss the final "]}", then you can actually fix it before parse it.
Here is an example code to illustrate:
with open("file.json","r",encoding="UTF-8") as f:
faulty_json_str = f.read()
fixed_json_str = faulty_json_str + ']}'
json_obj = json.loads(fixed_json_str)
I am trying to import a file which was saved using json.dumps and contains tweet coordinates:
{
"type": "Point",
"coordinates": [
-4.62352292,
55.44787441
]
}
My code is:
>>> import json
>>> data = json.loads('/Users/JoshuaHawley/clean1.txt')
But each time I get the error:
json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)
I want to end up extracting all the coordinates and saving them separately to a different file so they can then be mapped, but this seemingly simple problem is stopping me from doing so. I have looked at answers to similar errors but don't seem to be able to apply it to this. Any help would be appreciated as I am relatively new to python.
json.loads() takes a JSON encoded string, not a filename. You want to use json.load() (no s) instead and pass in an open file object:
with open('/Users/JoshuaHawley/clean1.txt') as jsonfile:
data = json.load(jsonfile)
The open() command produces a file object that json.load() can then read from, to produce the decoded Python object for you. The with statement ensures that the file is closed again when done.
The alternative is to read the data yourself and then pass it into json.loads().
It helped for me to add "myfile.seek(0)", move the pointer to the 0 character:
with open(storage_path, 'r') as myfile:
if len(myfile.readlines()) != 0:
myfile.seek(0)
Bank_0 = json.load(myfile)
I got same type of error after reading in a json file creating from python.
Same error occurred whether i read into a string and tried json.loads() or straight from file with json.load()
In my case, it turned out to be because I had written python booleans (False/True) straight out to the file.
Trying to read them back in again caused this error.
When i modified to valid json (true/false), json.load worked fine
Didnt see any SO questions with this as a possible cause for this error so adding here for reference.
You may use this function (it works with data):
def read_json_file(filename):
with open(filename, 'r') as f:
cache = f.read()
data = eval(cache)
return data
Or, you may put this in your code (it has the same effect):
def read_json_file(filename):
data = []
with open(filename, 'r') as f:
data = [json.loads(_.replace('}]}"},', '}]}"}')) for _ in f.readlines()]
return data
import json
file_path = "C:/Projects/Tryouts/books.json"
with open(file_path, 'r') as j:
contents = json.loads(j.read())
print(contents)
I am trying to open a JSON file in python with the following code:
import json
from pprint import pprint
with open('C:\\Users\\Dave\\Desktop\\data.json') as data_file:
data = json.load(data_file)
pprint(data)
But I get the follow error.
ValueError: Expecting property name enclosed in double quotes: line 1
column 2 (char 1)
I am using the test json {'a':1}
The call to JSON is fine. You can read more about opening JSONs with python.
If you replace your JSON with one of the good JSONs from that post, you will find the it runs just fine.
All you need to do is correctly format your data.
