Google this week expanded its Google Docs service to now include .docx and .xlsx file formats for uploading, adding to its list of supported files, including .doc, .odt, .xls, .ods., .ppt, .csv, .html, .txt, .rtf, and others.

"To import a .docx or .xlsx file, simply click the 'Uploa' button in Docs List menu, select your file, and voila!, "Google wrote in its blog. "We'll upload an convert your document for use in Google Docs. This is another great benefit of Google Docs - you don't have to worry about what format the file is in. Just upload it and we'll figure it out for you."

Google had already allowed users to open up .docx and .xlsx file formats from Gmail and Google search results, but this is the first time they've been able to do so in Google Docs automatically. Viewed as an important inclusion, the 'x' variants are the default format in Microsoft's Excel and Word 2007. Curiously missing, however, is support for PowerPoint 2007's .pptx file format.
