I don't officially support Excel 2003 XML file format, which is what this file is. The current file uses XSLT which is not scalable & chokes on large-ish files (like this document). And the only way to make this filter perform better is to write a new one from scratch, using raw C++ and ditch the current, poor-performing XSLT based filter.
So, our current filter is "better than nothing" but please don't expect a speedy file opening experience.
