## What is MPP File Viewer?

Open Microsoft Project and Primavera P6 schedules on Mac, iPhone, and iPad and inspect their Gantt charts, tasks, and resources. Export a PDF or CSV when you need to share the project information.

READ THE SCHEDULE
- Browse and search the task hierarchy
- Navigate a pinch-to-zoom Gantt timeline
- Inspect dates, durations, hierarchy, and relationships when present
- Review resources and assignments when present
- Share a PDF report, the Gantt chart as PDF or image, or a task-table CSV
- Print the Gantt chart

OPENS THESE FILES
- Microsoft Project MPP files (MPP8, MPP9, MPP12, MPP14) and MPT templates
- Microsoft Project XML (MSPDI)
- Primavera P6 XER exports and P6 XML
- MPX (Microsoft Project Exchange)

PRIVATE BY DESIGN
Files are processed locally on your device. GanttPeek has no account, advertising, analytics SDK, cloud parser, or activation server. It reads only the file you select and never writes back to it.

EXPLORE SAFELY
The fictional Harbor Studio Launch schedule is included with every install, so you can explore the interface and exports before opening a private file.

FORMAT NOTES
The MPP parser accepts the MPP8, MPP9, MPP12, and MPP14 binary families, including the shared Project 16.x / MPP14 family used by Project 2021, Project 2024, and the Microsoft 365 desktop client. Password-protected MPP files are not supported. Available fields depend on the format: binary MPP files expose fewer details than Project XML or Primavera files, and every gap is disclosed inside the app. GanttPeek is read-only and is not a certified scheduling or contractual-verification system.

ONE PROJECT FREE
Open one real project with every viewing and export tool. GanttPeek Pro opens every project, with an optional monthly or yearly subscription or a one-time lifetime purchase.

GanttPeek is independently developed by Eutopix Labs and is not affiliated with, endorsed by, sponsored by, or certified by Microsoft or Oracle. Primavera is a registered trademark of Oracle.
