Google Docs now supports Microsoft .docx and .xlsx files

Google Docs now supports uploading of documents in Microsoft’s most recent file format: the XML-based .docx and .xlsx that comes with Office 2007 (Windows) and 2008 (Mac).  This means that whenever someone sends you a Microosft Office Word document or an Excel spreadsheet with a file extension that ends with .x, you no longer have to convert it to a .doc or a .xls format just to upload it to Google Docs.  This also continues down the path of further removing the barriers of using Google Docs as one’s primary document-editing suite/repository.

No word yet on when Google’s online office suite will support .pptx files for PowerPoint presentations encoded in the XML goodness.
