I insert a image to the sheet, and transform sheet to datauri format. I get a error message.

function SaveElnFile(e) {
        var spreadSheet = GetSpreadsheet("ElnMain");
        var sheet = spreadSheet.activeSheet();
        spreadSheet.bind("excelExport", function (e) {
            var fileName = "ElnTemplate/" + GetDateTimeString() + ".xlsx";
            e.workbook.fileName = fileName;
            var workbook = new kendo.ooxml.Workbook({
                sheets: e.workbook.sheets
            });

            workbook.toDataURLAsync().then(function (dataURL) {
                xxxxxx....
            });
                e.preventDefault();
        });
        spreadSheet.saveAsExcel();
    }

Hi Vincent,

The images definition is part of the Workbook definition(https://docs.telerik.com/kendo-ui/api/javascript/ooxml/workbook/configuration/images). Those images are used in order to properly load the respective drawings of the sheets. Therefore, they are required to be present when having drawings placed somewhere in the Workbook.

From the snippet sent, I can see that you are passing the sheets definition to the kendo.ooxml.Workbook. The Workbook, however, does not contain images definition, which results in the observed error.

Here you could find a small Dojo sample, based on the snippet sent and configuring the exported Workbook with images:
