title: Import from XSLX to database using BizTalk Server 2013
body: <p>I am trying to create a sample app using <code>BizTalk Server 2013</code> that takes data from a <code>XLSX</code> file and saves them to a Sql Server database.
  I know that this can be done very fast using <code>DTSX</code> files but I need it with <code>BizTalk</code>. 
  I tried creating a <code>Custom Pipeline</code> and use it as a decoder but I failed to finish it.
  Can someone provide me a simple example how can I manage this?</p>
