  I am trying to create xlsx file using opennxml document. Data table contains one column with rich text in html string. example "<b>hi</b>" or <b>hi</b>
  How to append/set value to cellValue.Text. Please suggest any other approach to achieve this.</p>
  
  <pre><code>          Cell cell = new Cell() { CellReference =                           ExcelHelper.ColumnCaption.Instance.Get((Convert.ToInt32((UInt32)rowIndex) - 2), cIndex), DataType = CellValues.InlineString };
  
            cell.DataType = new EnumValue&lt;CellValues&gt;(CellValues.String);
  
           CellValue cellValue = new CellValue();                        
           cellValue.Text = data.Rows[rIndex][cIndex].ToString();//&lt;b&gt;hi&lt;/b&gt;
           cell.Append(cellValue);
  </code></pre>
