I am trying to create copy of selected workbook using createWorkbook(); which is not accepting .xlsb file format on excel online.
Error: "This workbook can not be open because file format may not be matching file extension"
It works properly on excel desktop application.
Could someone tell me what I did miss ?
Thanks in advance.
