Export Excel features has been introduced by Telerik Kendo since early of 2015. There will be a lot of customization if we need to handle the format we want. To customize the cell value in our preferred format, We need to make changes at excelExport event.
From here, we just call the saveAsExcel() method to trigger the event and export according to our preferred format for kendo grid data. Drop me a comment if you have question about the method above.

If you need to customize the error message in Telerik Report HTML5 Viewer, you are required to do the following tweaking to make it work. The best recommended way is hide/toggle the message and handle your own error message display according to the situation. This is related to the reason we want to hide the error message required when parameters are not fulfilled.
