Here's my code so far (VB):
Dim wb As New ClosedXML.Excel.XLWorkbook()
wb.Worksheets.Add(dTable, "export")
wb.SaveAs(location)
How can I remove just styling of the alternate rows (defaults to light blue)
Assuming you want to skip the header row, something like this should work before the save.
For i As Integer = 2 To wb.Worksheets.Worksheet("export").Rows.Count
wb.Worksheets.Worksheet("export").Row(i).Style.Fill.SetBackgroundColor(XLColor.White)
