title: How to save in excel 2010+ with NPOI 2.0
body: <p>I use NPOI for a long time and it always works but now I need to make it work with .xlsx and at least Microsoft Office 2010. It works but when I try to open the file it says that it's corrupt and I can not repair it. Here's the error I get :</p>
  
  <pre><code>Repaired Part: /xl/worksheets/sheet1.xml part with XML error.  Load error. Line 1, column 7550.
  Repaired Records: Cell information from /xl/worksheets/sheet1.xml part
  </code></pre>
  
  <p>Thanks for the help!</p>
