NüHelp converts Microsoft Word documents and HTML files to a CHM file. It's easy to use for beginners and has lots of options for advanced users.

1) Word 2003, 2007, 2010 or 2013.
2) HTML Help Workshop (included in zip file)
3) .Net 3.5 Client Profile (already on most computers)

*** Win7/8 users: After downloading the file, you will have to right click on the zip file, click properties, and then click the unblock button before unzipping. Otherwise the two chm help files in the zip file will either appear blank or say webpage not found.

Tip: Use NuZip to zip CHM files to prevent gmail from rejecting the attachment: http://sourceforge.net/p/nuzip

For programmers, a framework is provided that shows you how to link specific screens in your application to specific sections in the help file.

NüHelp is written in C#

  • Easy to use for beginners, and lots of features for advanced users.
  • No installation, just download zip file and run.

    NüHelp is a very usefull tool for creating CHM help without commercial authoring tools. It's easy to use, fast, and has great support: A problem due to national language support was fixed within a day, a feature request took two.

    I just got NuHelp last week 6/2014, and when i first used NuHelp it crashed on me. So i got a hold of support and by this last Monday (6/30/2014) they had a fix for me. Thanks Randall you guys rock. This Software is easy peasy and its fast and doesn't mess up the pics like others do. This was a 500 page document that was converted in less than a minute.
