title: HTML Input="file" Accept Attribute File Type (CSV)
body: <p>I have a file upload object on my page:</p>
  <pre><code>&lt;input type=&quot;file&quot; ID=&quot;fileSelect&quot; /&gt;
  </code></pre>
  <p>with the following excel files on my desktop:</p>
  <blockquote>
  <ol>
  <li>file1.xlsx</li>
  <li>file1.xls</li>
  <li>file.csv</li>
  </ol>
  </blockquote>
  <p>I want the file upload to <em><strong>ONLY</strong></em> show <code>.xlsx</code>, <code>.xls</code>, &amp; <code>.csv</code> files.</p>
  <p>Using the <code>accept</code> attribute, I found these content-types took care of <code>.xlsx</code> &amp; <code>.xls</code> extensions...</p>
  <blockquote>
  <p><code>accept</code>= application/vnd.openxmlformats-officedocument.spreadsheetml.sheet (.XLSX)</p>
  <p><code>accept</code>= application/vnd.ms-excel (.XLS)</p>
  </blockquote>
  <p>However, I cannot find the correct content-type for an Excel CSV file! Any suggestions?</p>
