title: generating items from json file in robot framework
body: <p>At the moment I have a custom library to read a json file and output a list. For example</p>
  
  <pre><code>def get(f):
    with open(f) as fd:
      data=json.load(fd)
    return [ k for k in data['d']['a'] ]
  </code></pre>
  
  <p>Then in RF, I call it like this</p>
  
  <pre><code>@{items}=    get     "f.json"
  </code></pre>
  
  <p>Is there a way I can do this natively in Robotframework without my custom function? I looked thru HttpLibrary but couldn't find anything relevant.</p>
