Navigating volume licenses was overwhelming—would my team use all the features, or were we just paying for extras? Plus, unauthorized file changes made it tough to maintain control. 

I needed a simpler solution, so I looked into Microsoft Project Viewer to help my team access and share project details without the full licensing hassle.

In this article, I’ll share my top 10 picks for the best Microsoft Project viewer software and their best features and limitations so you can make an informed decision.

What Should You Look for In Microsoft Project Viewer Software? 

All Microsoft Project viewers allow access to project files, but some offer extra features, making them true Microsoft Project alternatives. These added capabilities can greatly improve team collaboration and information sharing.

Here are some must-have features for project managers to consider:

• Open MPP files: Ensure compatibility with various file formats (.mpp, .mpt, .mpx, .xml) for complete project access
• Share project files: Look for options to export MPP files as Excel or CSV for easy sharing with non-Microsoft Project users
• Print project files: Ensure the viewer allows for easy printing of hard copies that you’ll need for meetings
• Support operating systems: Confirm compatibility with your OS, whether Windows, Mac, or Linux
• Display charts and reports: Check for essential project visuals like Gantt charts and resource allocation reports
• Access custom views: Ensure it can open custom views created in Microsoft Project for accurate data presentation
• Export files: Look for the ability to export files back to Microsoft Project or Excel for easy updates
• Handle large files: Be aware of any file size limitations that may restrict access to larger projects
• Integrate with cloud services: Verify compatibility with SharePoint, Google Drive, and OneDrive
• Support specific versions: Confirm compatibility with the versions of Microsoft Project you’re using

The 10 Best Microsoft Project Viewer Software

Here are my top 10 Microsoft Project viewer software options that allow you to view and share Microsoft project plans in detail: 👇🏼

1. ClickUp (Best for overall project management with integrations)

ClickUp offers both Microsoft Project file viewing capabilities and comprehensive project management features, making it an excellent choice for teams who want to work with MS Project files while having access to additional project management tools.

While it isn’t specifically designed as an MS Project viewer, ClickUp Project Management Software is a versatile platform worth considering when managing your projects.

I chose ClickUp as my top choice because it combines integration capabilities with collaboration tools, making it the best project management tool.

ClickUp Tasks

With ClickUp Tasks, you can break complex projects down into manageable tasks and align them with your workflow. Add custom fields, link dependent tasks, and categorize them by Task Types to ensure everything is organized just the way you need it. 

This customization goes beyond just viewing files to actively managing your projects.

ClickUp Integrations

As a ClickUp user, I love how ClickUp Integrations, which has over 1,000 tools, makes importing and exporting data effortless. 

Whether you’re bringing in tasks from Asana, Trello, or Jira, or syncing with Google Drive, Slack, and HubSpot, ClickUp keeps everything streamlined and accessible in one place.

Gantt charts are great for tracking timelines, while Kanban boards are perfect for visualizing workflow and managing task priorities.

ClickUp Views

While many Microsoft Project viewers mainly allow you to view .mpp files, ClickUp Views go beyond that. It lets you actively manage your projects with customizable views like Gantt charts and Kanban boards.
