I'm going to explain this in a number of different ways just to help clarify what I'm asking for: 1) When exporting Kendo grid to Excel, add support for setting the cell comments. 2) Please add support for a "comment" property to sheets.rows.cells. The value of the "comment" property would be used to set the cell comment in the generated Excel file. 3) In the link below, there is support for sheets.rows.cells.format. Add a similar property named sheets.rows.cells.comment that is used to set the cell comment in the exported Excel file. http://docs.telerik.com/kendo-ui/api/javascript/ooxml/workbook.html
