Script Description:

Uses Google docs API and Zoho Viewer API to open links with PDF, DOC, DOCX, XLS, PPT, RTF, ODT, ODS, ODP, CSV etc. files online in the browser itself without need for any third party software installed on your computer.

This script reduces the need for additional plugins required to open documents such as Acrobat reader plugin, etc. This is light weight on your system compared to using third party softwares, reducing browser / system crashes and load on your system. Read the privacy policy before installing.

Tested OK on:

(I came to know that it also works on Opera, Safari and Maxthon. But I did not use it on them yet. If you are using on these browsers, I will be pleased to hear feedback from you)

Supported File Formats:
