Remove ' ' from blank cells while export GridView to Excel using OpenXml in ASP.Net

Thanks for the reply. I'll try to be more clear. My gridview displays just fine. Cells that are empty show correctly as just blank. 

The problem is when I export that gridview table to an excel file, the empty cells contain &nbsp.

What I need help with is modifying the following VB code to write the excel file in a way that it doesn't insert &nbsp in place of empty cells. 

Protected Sub ExportExcel(sender As Object, e As EventArgs)
    Dim dt As New DataTable("GridView_Data")
    For Each cell As TableCell In GridView1.HeaderRow.Cells
        dt.Columns.Add(cell.Text)
    Next
    For Each row As GridViewRow In GridView1.Rows
        dt.Rows.Add()
        For i As Integer = 0 To row.Cells.Count - 1
            dt.Rows(dt.Rows.Count - 1)(i) = row.Cells(i).Text
        Next
    Next
    Using wb As New XLWorkbook()
        wb.Worksheets.Add(dt)
 
        Response.Clear()
        Response.Buffer = True
        Response.Charset = ""
        Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"
        Response.AddHeader("content-disposition", "attachment;filename=GridView.xlsx")
        Using MyMemoryStream As New MemoryStream()
            wb.SaveAs(MyMemoryStream)
            MyMemoryStream.WriteTo(Response.OutputStream)
            Response.Flush()
            Response.[End]()
        End Using
    End Using
End Sub

figured it out. I modified the following loop:

For i As Integer = 0 To row.Cells.Count - 1
    dt.Rows(dt.Rows.Count - 1)(i) = row.Cells(i).Text
Next

as follows:

For i As Integer = 0 To row.Cells.Count - 1
     dt.Rows(dt.Rows.Count - 1)(i) = row.Cells(i).Text.Replace(" ", "")
Next
