Hi Alan,

Please note that the Grid does not support the export of arbitrary Html to Excel. This limitation is mentioned in the Known Limitations section of the documentation. Excel itself does not support displaying arbitrary HTML so the way the the data is visualized in the Grid is different that the way Excel will show that data. 

Whether the configured title in the Grid will be displayed encoded could be controlled through the encodeTitles option. However, the titles of the Grid columns will be exported as is to the Excel file. If you need to unescape the configured titles string you could handle the exportExcel event and modify the titles:

excelExport: function(e) {
            var sheet = e.workbook.sheets[0];
            var cells = sheet.rows[0].cells;

            for(var i=0; i < cells.length; i++){
              if(sheet.rows[0].cells[i].value){
                sheet.rows[0].cells[i].value = htmlDecode(sheet.rows[0].cells[i].value)
              }              
            }
          },

Here is such Dojo example - https://dojo.telerik.com/@NeliK/epexUkoz.

As the observed behavior is expected I am changing the status of the item to 'Declined'. In case you have any additional quetsions do not hesitate to contact us.

I hope you will find the provided information helpful.
