Xlsx defaults to string datatype as cell format

[Balachandra_Pai]

Hi, i am new to golang. I am currently trying to export my data to an excel. I am using tealeg’s xlsx package for doing this. The rows i am trying to write to xlsx are multidimensional string objects. However, these data consists of date, float and int datatypes which is how i want it to be stored in excel. Below is an example of how my data looks like.

[
     "ESSEN",
     "2019-08-24 00:00:00",
     "0.9706181883811951"
   ],
   [
     "ESSEN",
     "2019-08-24 00:00:00",
     "0.9706181883811951"
   ],
   [
     "ESSEN",
     "2019-08-24 00:00:00",
     "0.9706181883811951"
   ]

Below is the code:

// Create header row and insert values strings as bold string.
headerRow := sheet.AddRow()
headerStyle := xlsx.NewStyle()
headerStyle.Font.Bold = true
for _, val := range headers {
	cell := headerRow.AddCell()
	cell.SetValue(val)
	cell.SetStyle(headerStyle)
}

// Put remaining row values.
for _, rowData := range rows {
	row := sheet.AddRow()
	for _, val := range rowData {
		cell := row.AddCell()
		cell.SetValue(val)
	}
}

After exporting these data to excel i see that these datatypes are stored as string rather than Date, float or int. Is there anyway to solve this problem?
