I have developed an application to export data using the excelHtml5 export button. The spreadsheet seems to be fine except for cells containing numeric data. The numeric data will not work with the sum function in excel. I have attempted to change the cell type in the spreadsheet to numeric. The only way it will work is if I overtype the numeric data in the spreadsheet.
I have confirmed the underlying data in the table is numeric.
Is there some type of customization that needs to be done?
Thanks,
