ClosedXML throwing out of memory exception when exporting 73000 records

Exception is coming at this particular line of code -

wb.Worksheets.Add(DynamicSource);

dynamicsource is the datatable that has all the data to be exported

As a work around to out of memory problem, I am directly saving excel to physical location without doing anything with memory stream. I am getting a different exception now when saving data to excel. There is no NULL data in the dataset. I tried to loop through each and every row and column in dataset to replace hexadecimal value but that taking forever to run.

Exception: ’ ', hexadecimal value 0x0B, is an invalid character

Code snippet – using (XLWorkbook wb = new XLWorkbook()) { wb.Worksheets.Add(DynamicSource); wb.SaveAs(@“C:\Work\Grid1.xlsx”); }
