Cmdlet Help Editor tool

Intoducing the Cmdlet Help Editor V1.0


Cmdlet Help Editor enables you to create help topics for Windows PowerShell cmdlets in the XML format that Windows PowerShell reads. Help text created in Cmdlet Help Editor can be displayed immediately by a Windows PowerShell get-help command without any additional transforms or formatting.


By reflecting on a Windows PowerShell snap-in (PsSnapin) assembly, Cmdlet Help Editor creates a customized documentation interface that includes the cmdlets in the snap-ins, their parameters, and parameter attributes.


Cmdlet Help Editor was designed for Windows PowerShell cmdlet developers to make it easy to create excellent cmdlet help. This tool is made available free of charge, but it is not warranted or supported by Microsoft.

You can download the tool from

  • I can't wait to try this out.  Creating cmdlet help was one of the most painful tasks I've ever had to do.  We all know how important documentation is and anything that makes it easier to generate will be a great boon.

  • EXCELLENT WORK. Just created a help file for the SAPIEN Extensions ( in a few minutes. This is a great tool and the effort is GREATLY appreciated.

  • We loved the tool, I was able to create help and tutorial for our internal users to get to the point sort of thing on our build environment. Does the Help editor tool will be part of the final release? Also any chance to have command line interface that will east many steps.


  • This thing is FANTASTIC!  Thank you!

  • Hi Wassim, great tool! I do have another problem however. I have thousands of lines of PowerShell code that I want to get documented in a consistant way. There are utility libraries and there is a whole bunch of code utilizing these libraries (.ps1 files).

    Any ideas on how to get this documented etc.?

    Thanks, Serge

  • Great tool (but I was expecting it;) - do I have to save the xml file for the whole Snapin or can I save the xml file for each individual Cmdlet?


  • Very nice tool and slick UI.  BTW I notice on parameters there are two check boxes for "Globbing" and "Original Globbing" the latter of which is disabled.  So what's that all about?  Are there globbing changes for the next version of PowerShell?

  • Sorry for the delay in responding. I was out of office and now catching up:

    Thank you all for trying the tool.

    Serge, we should have a way for you in our V2 version of PowerShell. Please stay tuned.

    Peter, you can save the file for each individual cmdlet using the Export XML button. later you can merge them all through a simple script. Please refer to the documentation that was released with the tool.

    Keith, The Original Globbing loads the value you have in the loaded help file. Please refer to the documentation file for more info.

  • Hi,

    I have worked with Shay over the weekend and the issue he had is that he did not have .Net 3.0 installed on his machine. After he installed the Framework, the app worked for him.
