Excel Spreadsheets & Word Docs Supported
In addition to adding images and pdf's on web pages, MS Word documents (.docx) and Excel spreadsheets (.xlsx) are now supported. To add a file, go to the media library and click "add new media file". Please keep in mind that not everybody has MS Office and thus can't open these file types. So unless there is a pressing need, it's probably best to convert to the universal pdf format as was the original intent.
