Many Excel project plans have too much detail to cleanly fit onto a single page Gantt chart. OnePager Express can build large project timelines and Gantt charts that span multiple pages, which allows you to show as much detail as you need to without your reports getting too cluttered.
If you prefer, you can insert page breaks into your Gantt chart by hand, or you can have OnePager Express automatically fit your timeline to the ideal number of pages.
