title: GruntJS assemble parsing Json file by helper to partial
body: <p>I want to parse json file via helper to partial. I am currently using technique from this site:</p>
  
  <p><a href="http://assemble.io/helpers/helpers-data.html" rel="nofollow">Parsing Json data into partial</a></p>
  
  <p>It works very well but I would like to parse entire json file:</p>
  
  <pre><code>{{#parseJSON jsonfile}}
  </code></pre>
  
  <p>instead of doing this:</p>
  
  <pre><code>{{#parseJSON '{"id": "firstname", "label": "First name"}'}}
  </code></pre>
  
  <p>#each helper works by passing Json file</p>
  
  <pre><code>{{#each jsonfile}}
    {{&gt; partial}}
  {{/each}}
  </code></pre>
  
  <p>Is it possible to do this with custom helper?</p>
