Microsoft Project versus PrimaveraThrough October 16, 2026
87% of schedules uploaded to our free tools are .mpp or other files not in XML, and 11% are XML
Of 299 free and anonymous schedules uploaded to our free tools (the Schedule Health Check, the MPP viewer and Onplana Schedule). The upload records every file that is not XML as .mpp, so Primavera .xer uploads are counted under .mpp here, and Primavera XML under XML. This split cannot tell Microsoft Project from Primavera. The Microsoft Project and Primavera split is published here once each holds at least 20 uploads whose application our converter named.
