Convert Rtf to HTML

Question

We have a crystal report that we need to send out as an e-mail  but the HTML generated from the crystal report is pretty much just plain ugly and causes issues with some e-mail clients   I wanted to export it as rich text and convert that to HTML if it s possible   Any suggestions

I would check out this tool on CodeProject RTFConverter   This guy gives a great breakdown of how the program works along with details of the conversion   Writing Your Own RTF Converter

I am not aware of any libraries to do this  but I am sure there are many that can  but if you can already create HTML from the crystal report why not use XSLT to clean up the markup

I think you can load it in a Word document object by using  NET office programmability support and Visual Studio tools for office   And then use the document instance to re-save as an HTML document   I am not sure how but I believe it is possible entirely in  NET without any 3rd party library

UPDATED   I got home and tried the below code and it does not work   For anyone wondering  the clipboard does not just magically convert stuff like I d hoped   Rather  it allows an application to sort of  upload  a data object with a variety of paste formats  and then then you paste  which in my metaphor would be the  download   the program being pasted into specifies its preferred format   I personally ended up using this code  which has been recommended previously  and it was enormously easy to use and very effective   After you have imported the code  in VStudio  Project -  Add Existing Files  you then just go html to rtf like this   return HtmlToRtfConverter ConvertHtmlToRtf myRtfString     or the opposite direction   return RtfToHtmlConverter ConvertHtmlToRtf myHtmlString      below is my previous incorrect answer  in case anyone is interested in the chronology of this answer haha   Most if not all of the above answers provide comprehensive  often Library-based solutions to the problem at hand  I am away from my computer and thus cannot test the idea  but one alternative  cheap and vaguely hack-y method would be the following   private string HTMLFromRtf string rtfString                Clipboard SetData DataFormats Rtf  rtfString               return Clipboard GetData DataFormats Html                Again  not totally sure if this would work  but just messing around with some html on my iPhone I suspect it would   Documentation is here   More in depth explanation docs RE the getting and setting of data models in the clipboard can be found here    Yes I am fully aware I m here years later  but I assume this question is one which some people still want answered

If you don t mind getting your hands dirty  it isn t that difficult to write an RTF to HTML converter   Writing a general purpose RTF- HTML converter would be somewhat complicated because you would need to deal with hundreds of RTF verbs   However  in your case you are only dealing with those verbs used specifically by Crystal Reports   I ll bet the standard RTF coding generated by Crystal doesn t vary much from report to report   I wrote an RTF to HTML converter in C    but it only deals with basic formatting like fonts  paragraph alignments  etc  My translator basically strips out any specialized formatting that it isn t prepared to deal with  It took about 400 lines of C    It basically scans the text for RTF tags and replaces them with equivalent HTML tags  RTF tags that aren t in my list are simply stripped out  A regex function is really helpful when writing such a converter

There is also a sample on the MSDN Code Samples gallery called Converting between RTF and HTML which allows you to convert between HTML  RTF and XAML
