Free Schedule Viewer

The Free Schedule Viewer opens .XER and .XML schedule files in your browser. It is free, needs no sign-in, and does not upload your file. It shows each activity under its WBS, with a Gantt, the data date, the logic and the total float in the file.

Your file stays on your computer. It is read by this browser tab and never uploaded to Pathizer.

How it works

  1. Step 1

    Drop your schedule

    A .XER or .XML schedule file, a Microsoft Project .xml, or a USACE SDEF file, in the box at the top right. No account, no sign-up. From an .mpp, use Save As XML in Microsoft Project first.

  2. Step 2

    It opens in your browser

    Your computer reads the file. It is never uploaded to Pathizer or anyone else, and closing the tab clears it.

  3. Step 3

    Browse it like your scheduling software

    Every activity under its WBS, with a Gantt, the data date, search by activity, contractor or WBS, and each activity's predecessors and successors. Click one to jump to it.

  4. Step 4

    See the stored float

    Each activity's total float as the file stored it. Nothing is rescheduled or recalculated.

In a project workspace, Pathizer compares each schedule update with the one before it and drafts the update narrative and reports for your scheduler to review. The free Health Check and Update Compare run in your browser, like this viewer. See the free tools.

Files it opens

A browser cannot open a Microsoft Project .mpp file. Open it in Microsoft Project and choose File, Save As, XML. Then drop the .xml file here.

If a .XER file has more than one project in it, the viewer tells you which one it is showing.

  • .XER files. This is the plain text file that professional CPM scheduling software exports.
  • .XML schedule files, including Microsoft Project XML (.xml)
  • USACE SDEF files (.sdef, .sdf or .std)
  • Files up to 20 MB. Bigger files are turned away, because a browser tab cannot lay them out well.

What you see

Dates, durations and total float are shown exactly as the file has them. Nothing is recalculated. What you see is what the scheduling software last worked out.

If accented letters, Arabic or Cyrillic text look wrong, change the text encoding. The choices are Automatic, Western (Windows-1252), Arabic (Windows-1256), Cyrillic (Windows-1251) and Central European (Windows-1250).

  • Every activity, under its WBS branch, in a table
  • A Gantt chart beside it, with the data date marked
  • The columns you choose
  • Search by activity, contractor or WBS
  • Pick an activity to see what comes before and after it (its predecessors and successors). Click one to jump to it.

What stays on your computer

  • Your browser opens the file in this tab.
  • It is not uploaded to Pathizer or anyone else.
  • Nothing about the file is saved. Closing the tab clears it.
  • You do not need an account.
  • Ad tags do not load on this page.

Step by step

  1. Export the schedule from your scheduling software as a .XER or .XML file. Or use the .XER file a contractor sent you.
  2. Drop it in the box at the top right, or click the button to choose it.
  3. Check the project name, data date and activity count above the table.
  4. Open the WBS, pick your columns and search for the activities you need.
  5. Pick an activity to follow what comes before and after it.

What it does not do

The viewer opens one file and shows it.

  • It does not edit or save the schedule. P7 Free Scheduling opens a schedule for editing.
  • It does not check how well the schedule is built. The free Health Check runs the DCMA checks one file can answer.
  • It does not compare updates. The free Update Compare lists what changed between two updates.
  • It does not explain why a date moved.

Questions

Is the viewer free?
Yes. It costs nothing. You do not need an account or a card.
Which files does it open?
.XER files, .XML schedule files, Microsoft Project .xml files and USACE SDEF files (.sdef, .sdf or .std). Each file can be up to 20 MB.
Can I edit the schedule here?
No. The viewer shows the file and does not change it. To edit a schedule, open it in P7 Free Scheduling, which saves .XER.
Is my schedule uploaded?
No. Your browser opens the file in this tab. It is never uploaded. Closing the tab clears it.
Can I open an .mpp file?
Not directly. A browser cannot read .mpp files. In Microsoft Project, choose File, Save As, XML. Then open the .xml file here.
Does it recalculate the schedule?
No. It shows the dates and total float saved in the file, exactly as the scheduling software last worked them out.
What does the Report button show?
What Pathizer would cost each month for a project this size, at the published price. Size here means the number of activities, and the viewer counts them for you. Very large schedules are priced by quote, and the Report says so.

The free tools cost nothing. Pathizer Enterprise costs $250 a month for up to 2,500 activities, with no charge per seat. See pricing.
