I'm currently integrating some code from [1], i.e. there will be an Extractor class for Excel, but the code will differ a lot from that quick and dirty SO hack ...The reason why this might not work for you is the AlternateContent tag, which wraps a lot of tags in newer Office releases.The methods which are based on scanning the zip directories or package relations should be affected by this.
