Create an Excel Spreadsheet (XSLX) in C# -- server side
<p>So, this question has been asked before, but wait -- it's not a duplicate! (at least I don't think so).</p>

<p>I need to create Excel files (xlsx files).  The library must be suitable to run on a server, it must be 64-bit capable, </p>

<p><em>and</em> I have to be able to distribute it with a closed-source (for profit) product.</p>

<p>I had been hoping to use ExcelPackage on CodePlex, but it's published under GPL, and as nearly as I can tell, without the "component library exception", so I'm pretty sure that means I can't use it.</p>

<p>Can anyone recommend a good, server-compatible, 64-bit library that I can use in my closed-source app?</p>
