gProjectViewer

gProjectViewer is a powerful and free Chrome extension designed to open and view Microsoft Project (MPP) files without requiring Microsoft Project software. It replicates the familiar MS Project interface, enabling users to access Gantt Charts, Network Diagrams, Task and Resource Usage, Project Calendars, Resource Sheets, and various Project Reports directly within their browser.

Beyond viewing, gProjectViewer offers in-app options to unlock advanced sorting, filtering, and multiple project views, as well as the capability to create new or edit existing project plans and save them in MPP format. Compatible with a wide range of MS Project versions and integrated with popular cloud storage services (One Drive, Google Drive, Box, Dropbox, SharePoint), it serves as a cost-effective alternative for project management professionals worldwide. Multi-language support broadens its accessibility across different user bases.
