title: How to unparse result after iterating through specific data with papaparse?
body: <p>I'm trying to use PapaParse to parse a local CSV file and iterate through the JSON in order to only output specific data from the file. </p>
  
  <p>Example: I only want Column "Mill Description" to match adidas &amp;&amp; Champion, all other data is discarded.</p>
  
  <p>If you need more clarification don't hesitate to ask, I will be checking here periodically.</p>
  
  <p>CSV File: <a href="https://ufile.io/ze7xl" rel="nofollow noreferrer">https://ufile.io/ze7xl</a></p>
  
  <pre><code>papa.parse(file, {
    worker: true,
    header: true,
    transformHeader: true,
    step: function(result) {
      var data = result.data;
      for (var i = 0; i &lt; data.length; i++) {
        var millDescription = JSON.stringify(data[i]["Mill Description"]);
        if (
          millDescription.includes("adidas") ||
          millDescription.includes("Champion")
        ) {
        // This is where I need help
        }
      }
    },
    complete: function(result, csv) {
      console.log("parsing complete read: ", result, csv); // Nothing is passed to here yet.
    }
  });
  </code></pre>
