Document Previewer 作者: Himank

Opening any link to a doc, docx, ppt, pptx, xls, xlxs or pdf file will open a page giving the user the option to preview or directly download the file.

WARNING: This add-on uses the preview feature of Google docs. Any file previewed using this add-on will be made accessible to Google. This could be a privacy concern especially when previewing personal files.
