I would like to integrate a viewer tool for viewing files in PDF, MS Excel, and MS Word formats. I am developing a website that store manuals on our server and I would like visitors to be able to view these manuals online instead of downloading. I found a tool named ViewerJS that can view PDF and Open Documents online. However the tool doesn't support Microsoft Office.
- Must support displaying at least:
- Prefer Open Source and Gratis
- Licensed software with price up to $2000USD would possibly work.
