    Resolved Issues in Merlin

  • Some mpp files could not be opened by Merlin.
  • MS Project could not open from Merlin generated XML files containing % in duration fields or some special character in a task’s title.

Merlin: MS Project MPX vs XML as exchange formats to Merlin (Mac)

Merlin’s compatibility to Windows and mainly MS Project is very important not only to us but also to our users.  What if you were practicing project management on windows and have lots of existing projects which you would like to use now on your Mac? Or what it you have to forward a project to a Windows user needing to edit it further in MS Project? That’s fine. With Merlin you can handle both situations just as well.

Merlin opens MS Project .mpx, .mpp, .xml file formats and exports in .xml, .mpx.

Are you wandering which file format should be preferred? The answer is easy:
We -and even Microsoft- recommend to use the XML format as it is open and reliable.

Only when trying to exchange files with MS Project users of older versions than MS Project 2000, you would need to choose a legacy format like mpx.

Simple, isn’t?

MS Project import – User defined fields

If you have MS Projects containing user defined columns and need to edit them in Merlin, simply save those files in the MS Project XML exchange format. Open the XML file later on in Merlin, click any activity in your project and check the ‘User Defined Fields’ tab. You will find them all listed there displaying their contents.

Please note:

MS Project will not save the custom titles into the XML file, so Merlin displays their column identifier.



  • If you have only one user defined field simply edit its title in the ‘User Defined Fields’ tab
  • If you have imported various user defined fields at once, you may want to display first the columns on the outline to know which column title fits which content.

Isn’t great?  Not only seamless import of MS Project  files but also to such a deep extent.  Merlin never ceases to amaze me 🙂
