Millions of people use Google Docs Viewer every day to quickly view PDFs, Microsoft Word documents and PowerPoint presentations online. Viewing files in your browser is easier, generally far more secure than downloading and opening them on your own computer, saves time and reduces clutter on your hard-drive.
Now, in addition to support for the major Microsoft formats DOC, DOCX, PPT, PPTX, XLS and XLSX, Google has added support for a further twelve file types.
Microsoft Excel (.XLS and .XLSX)
Microsoft PowerPoint 2007 / 2010 (.PPTX)
Apple Pages (.PAGES)
Adobe Illustrator (.AI)
Adobe Photoshop (.PSD)
Autodesk AutoCad (.DXF)
Scalable Vector Graphics (.SVG)
PostScript (.EPS, .PS)
TrueType (.TTF)
XML Paper Specification (.XPS)
