It is very important for me to have inline text formatting in HTML to be translated to Excel. Sometimes I have the formatting specified in style attributes and sometimes I have <font> tags, or <b>, <u>, and <i>. The most important inline font stylings for me are size, underline, colour, bold and italic.
Yes, this is possible, this feature is in "Completed" stage.
Please try the following example:
ExcelFile ef = new ExcelFile( );
ExcelWorksheet ws = ef.Worksheets.Add("Sheet1");
ExcelCell cell = ws.Cells["A1"];
cell.SetValue("<span ><strong>Foo</strong> <em>Bar</em></span>", LoadOptions.HtmlDefault);
I hope this helps.
