Did you try to open your xlsx file in a text editor? Does it seem like a regular xml file?

Solution 2

Are you sure your reading an XML file?

the xlsx is an Excel 2007 - 2010 file extension

This so called solution is really a comment. By the way, excel can open some xml files too. So, if you save a proper xml as an 'xlsx' file, it will be opened by excel.
