title: Upload Excel 2013 Workbook to website hosted on Azure
body: <p>Does anyone have guidance and/or example code (which would be awesome) on how I would go about the following?</p>
  
  <p>With a Web application using C# / ASP.NET MVC and hosted on Azure:</p>
  
  <ol>
  <li>Allow a user to upload an Excel Workbook (multiple worksheets) via a web page UI</li>
  <li>Populate a Dataset by reading in the worksheets so I can then process the data</li>
  </ol>
  
  <p>Couple of things I'm unclear on:</p>
  
  <ol>
  <li>I've read that Azure doesn't have ACEOLEDB, which is what Excel 2007+ requires, and I'd have to use OPEN XML SDK. Is this true? Is this the only way?</li>
  <li>Is it possible to read the file into memory and not actually save it to Azure storage?</li>
  </ol>
  
  <p>I DO NOT need to modify the uploaded spreadsheet. Only read the data in and then throw the spreadsheet away.</p>
