I use [EPPlus](http://epplus.codeplex.com/) for Excel file generation.

I mean I need to convert HTML text (bold, italic, font color, name, size parameters) to Excel Cell. I suppose it needs to create the multi-styled cell, like:

cell text is "hello!"  

the style I want is:

```
he - bold  
ll - italic  
o! - red colored font  

```

or (more complex)

```
hello! - bold  
ll - italic (also bold)  
o! - red colored (also bold)  

```

I know about MS OpenXML library (it allows me to do what I need). This is good but bit more complex library for implementation.
