Project Online has retired. Bring your schedule here.

Why teams are moving now

Microsoft retired Project Online on September 30, 2026 (Microsoft's lifecycle page). Large programs need a proper replacement decision. Many projects never needed that: they needed a schedule the people around the project can open. That is what gantt-chart.io is for.

Move a schedule in three steps

1. Save the plan as Microsoft Project XML. Open the plan in Microsoft Project on your desktop. Choose File, then Save As, and pick XML Format (*.xml). gantt-chart.io reads XML, not binary .mpp files, so an .mpp has to be saved as XML first.
2. Import the XML into gantt-chart.io. Sign in free and open a project. In the Outline panel choose Import data, pick the XML file (up to 2 MB), check the preview, then import. Phases become lanes, and each task keeps its start and finish dates, percent complete, owner and its links to other tasks.
3. Check it, then share a read-only link. Compare the dates on your key tasks with the original. The critical path is drawn from the imported links. Then share a read-only link: the people who open it don't need an account or a Microsoft licence.

What comes across

• Tasks with their start and finish dates
• Phases as lanes, and sub-phases as groups inside them
• Percent complete and milestones
• Owners, from the plan's resource assignments
• Task links (finish-to-start, start-to-start, finish-to-finish and start-to-finish) with their lag in days
• A critical path drawn from those links

What doesn't

• Portfolio views, resource pools and resource levelling
• Cost, budget and earned value fields
• Custom working calendars: dates come in as calendar dates, and lags are rounded to whole days
• Binary .mpp files: save them as XML first

Frequently asked questions

When did Project Online retire?

Microsoft's lifecycle page lists Project Online's retirement date as September 30, 2026.

Do my task links and critical path come across?

Yes. Links between tasks in the XML file are imported with their type and lag, and gantt-chart.io draws the critical path from them. A link to a summary row (a phase) has no bar to point at, so it is left out.

Can I import an .mpp file?

No. Open it in Microsoft Project and save it as XML Format (*.xml), then import the XML.

What does it cost?

The Free plan holds 1 saved project with 1 AI credit a month and no downloads. Solo is a flat $12 a month for one person, with unlimited projects and downloads, including Microsoft Project XML.

Can I get my plan back out?

On Solo you can download the plan as Microsoft Project XML, CSV or JSON, or print it to PDF from your browser.

Is this a replacement for a whole PMO?

No. gantt-chart.io is for projects that need a clear, shared schedule. If you need portfolio reporting, resource pools or earned value, plan a fuller replacement for those programs.
