Open the file with any text editor. Add a [ at the very beginning of the file, and a ] at the very end. This will transform the data you have into an actual valid JSON array.
Then use the json module to work with it.
(EDITED CORRECTED VERSION BASED ON COMMENTS, thx @martin-novosad)
import json
with open("example.json") as f:
arr = json.load(f)
# Do nifty stuff with resulting array.

Python JSON
Python has a built-in package called json, which can be used to work with JSON data. ... If you have a JSON string, you can parse it by using the json.loads() method.

The json.load() method (without "s" in "load") can read a file directly:
import json
with open('strings.json') as f:
d = json.load(f)
print(d)
You were using the json.loads() method, which is used for string arguments only.
The error you get with json.loads is a totally different problem. In that case, there is some invalid JSON content 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.

You're trying to read the string "data.txt". What you want is to open and read the file.
import json
with open('data.txt', 'r') as data_file:
json_data = data_file.read()
data = json.loads(json_data)

Try:
data = json.load(open("data.txt", 'r'))
json.loads interprets a string as JSON data, while json.load takes a file object and reads it, then interprets it as JSON.

Based on reading over the documentation again, it appears you need to either change the third line to
json_data = json.loads(text)
or remove the line
text = json_file.read()
since read() causes the file's index to reach the end of the file. (I suppose, alternatively, you can reset the index of the file).
