Microsoft Project Integration


Celoxis is a great alternative to Microsoft Project. Celoxis' integration with Microsoft Project is one of the most comprehensive in the industry. If you understand how it works, you can achieve a perfect 2-way synchronization with Microsoft Project thus getting the best of both worlds.

Importing from Microsoft Project

You can create a project directly from a Microsoft Project file by clicking on (Top MenuProjectImport Microsoft Project) or import tasks into an existing project (Project OptionsImport Microsoft Project).

When you import a Microsoft Project file (XML or MPP), Celoxis will import:

  • Parent-child relationships
  • Dependencies including lead-lag times
  • Constraints
  • Resource assignments
  • The default baseline
What is not imported:
  • Calendar options - e.g. hours/day, days/month, etc.
  • Resource list
  • Custom fields
  • Non-default baselines
  • Calendars and exceptions
  • Time-phased data

Import field mappings

While the field mappings in most cases are self-explanatory (they have the same name in MS Project and Celoxis), some fields deserve a special mention:

MS ProjectCeloxis
% Work Complete% Comp
PriorityVery High(700+), High(600+), Normal(500), Low(400+), Very Low(0+)
Task ModeManually Scheduled

Understanding Deviations

Celoxis and Microsoft Project while similar in many ways are different in certain areas (see the list of what is not imported above) and that can cause certain surprises. If dates do not match in Celoxis after importing, ensure that:

  • Work calendars and exceptions in MS Project and Celoxis match. Note that MS Project does not support time-zones or fractional non-working times.
  • You are not using any of the options or features in Microsoft Project that Celoxis does not import
  • You mapped the resources correctly during the import

Exporting to Microsoft Project

When you export a project to Microsoft Project (Project OptionsExport Microsoft Project), the following will be exported:

  • Parent-child relationships
  • Dependencies including lead-lag times
  • Constraints
  • Resource assignments
  • The default baseline
  • Work Calendars and Exceptions
  • Resources and their individual exceptions
What is not exported:
  • Custom fields
  • Inter-project predecessors
  • Fields that have no corresponding field in Microsoft Project (e.g. workspace, budget, etc.)
  • Resource allocation in hours is changed to % because Microsoft Project does not support allocation in hours

Export field mappings

While the field mappings in most cases are self-explanatory (they have the same name in MS Project and Celoxis), some fields deserve a special mention:

  • You are not using any of the options or features in Microsoft Project that Celoxis does not import
  • You have not allocated resources in hours and only used % in Celoxis. Microsoft Project does not support allocation in hours.
