title: Replacing empty Strings with custom text (PapaParse)
body: <p>Is there a way PapaParse can replace empty Strings to a custom text? I want to export JSON to CSV but when there is a field with no data in it I want to export something like &quot;MISSING DATA&quot; automatically without going trough my array with a loop checking if there is data</p>
  <p>those are my options:</p>
  <pre><code>this.csvFile = this.papa.unparse(jsonData,this.options);
  
  
    options = {
    quotes: false, //or array of booleans
    quoteChar: '&quot;&quot;',
    delimiter: &quot;;&quot;,
    header: false,
    skipEmptyLines: true,
  </code></pre>
  <p>}</p>
