About GAN
GanttProject is a free, open source planner for Windows, macOS and Linux. Teams, schools and small firms plan in it, and its .gan files go to people who don't have it, often on a phone.
A GAN is XML: the tasks nested as the outline puts them, each with its start, length, progress, color and notes, the dependencies between them with their lags, the weekends and holidays, the resources and their roles, and who works on what.
Filepeek reads it in your browser with a reader of its own. The tasks open with their outline, durations, dates, % complete, predecessors and resources, and their bars run along a timeline beside them: summaries, milestones as diamonds, links with their lags and the critical path in coral, worked out from the dependencies, since GanttProject keeps no critical path. Resources has a tab of its own, and Export saves CSV, Excel, Project XML, or the chart as PDF or PNG.

Questions
How do I open a GAN file without GanttProject?
Drop it on this page or press Peek a GAN. It opens as its Gantt chart in your browser, on a phone too, where GanttProject doesn't run.
How do I convert GAN to Excel or Microsoft Project?
Open it, choose Export, then Save the tasks and resources as Excel, Save the tasks as CSV, or Save as Project XML, which Microsoft Project and ProjectLibre open.
Can I save the chart as a picture or a PDF?
Yes. Save the chart as PNG takes the timeline at its zoom with the tasks beside it, and as PDF it's fit to A3 or tabloid pages, as many as the tasks need.
Can I edit it?
Filepeek only shows it. GanttProject is free on Windows, macOS and Linux.
