title: Converting XLSX file using to a CSV file
body: <p>I need to convert an XLSX file to another CSV file.
  I've done a lot of research on how to do this process, but I did not find anything that suited me.
  I found this Github Gist only <a href="https://gist.github.com/andrewmurray/b63b7592386cb67124d1" rel="nofollow noreferrer">Convert an Epplus ExcelPackage to a CSV file</a></p>
  <p>That returns an Array of binary. But apparently it does not work any more.</p>
  <p>I'm trying to load Array using <code>LoadFromCollection</code></p>
  <pre><code>FileInfo novoArquivoCSV = new FileInfo(fbd.SelectedPath);
  var fileInfoCSV = new FileInfo(novoArquivo + &quot;\\&quot; + nameFile.ToString() + &quot;.csv&quot;);
  
  using (var csv = new ExcelPackage(fileInfoCSV))
  {
      csv.Workbook.Worksheets.Add(nameFile.ToString());
      var worksheetCSV = csv.Workbook.Worksheets[1];
  
      worksheetCSV.Cells.LoadFromCollection(xlsx.ConvertToCsv());
  }
  </code></pre>
