<pre><code>let directoryContents = try NSFileManager.defaultManager().contentsOfDirectoryAtURL( documentsUrl, includingPropertiesForKeys: nil, options: [])
let xlsxFiles = directoryContents.filter{ $0.pathExtension == "xlsx" }
let xlsxFileNames = mp3Files.flatMap({$0.URLByDeletingPathExtension?.lastPathComponent})

var fileManager = NSFileManager.defaultManager()

do {
    try fileManager.copyItemAtPath(xlsxFiles[0].absoluteString, toPath: NSBundle.mainBundle().resourcePath! + xlsxFileNames[0] + ".xlsx")
}
catch let error 
{
    print(error)
}
</code></pre>
