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.

March 15, 2022extracting data from 100+ pdf files
I actually just built a program to extract lab test data from PDFs for work and dump it into an ordered csv file. I won’t go into the nitty gritty details of everything I did, but it all started with the use of the pdfplumber package. It’s not too difficult to use. The GitHub will explain all of the necessary details. Using .extract_text() will give you all of the text as a single string with \n representing line breaks. From there it’s up to you to write the appropriate text parsing using regex and such. Note that pdfplumber won’t work in scanned PDFs. They have to have been computer generated. One nice thing about pdfplumber is using .extract_words() will generate a list of dictionaries for every word in the pdf. The dictionaries have location info which you can use to help crop the pdf based on the relative location of what you’re looking for to other nearby words. More on reddit.com

October 4, 2020How to parse JSON strings in Python
To parse a JSON string in Python, we can use the built-in **`json`** module. This module provides two methods for working with JSON data:
- **`json.loads()`** parses a JSON string and returns a Python object.
- **`json.dumps()`** takes a Python object and returns a JSON string.
