title: Python JSON parser error: json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)
body: <p>I need some help parsing JSON file.  I've tried a couple of different ways to get the data I need.  Below is a sample of the code and also a section of the JSON data but when I run the code I get the error listed above.</p>
  
  <p>There's 500K lines of text in the JSON and it first fails about about 1400 lines in and I can't see anything in that area section to indicate why.</p>
  
  <p>I've run it successfully by only checking blocks of JSON up to the first 1400 lines and I've used a different parser and got the same error.</p>
  
  <p>I'm debating if it's an error in the code, an error in the JSON or a result of the JSON being made of different kids of data as some (like the example below) is for a forklift and others for fixed machines but it is all structured just like below.</p>
  
  <p>All help sincerely appreciate.</p>
  
  <p>Code:</p>
  
  <pre><code>import json
  
  file_list = ['filename.txt'] #insert filename(s) here
  
  for x in range(len(file_list)):
  
      with open(file_list[x], 'r') as f:
          distros_dict = json.load(f)
  
  #list the headlines to be parsed
  for distro in distros_dict:
      print(distro['name'], distro['positionTS'], distro['smoothedPosition'][0], distro['smoothedPosition'][1], distro['smoothedPosition'][2])
  </code></pre>
  
  <p>And here is a section of the JSON:</p>
