Hi Malathi,
Thank you for your interest in Syncfusion products.
Currently In our XlsIO, we do not have support to save the excel file to share point directly, instead we provide support to save the excel file as stream. Please see the below code snippet. Also we have attached the sample for the same. Could you please try this sample and let us know if this helps you.
Code Snippet:
ExcelEngine excelEngine=new ExcelEngine();
FileStream fileStream = new FileStream(fileName, FileMode.Open);
IWorkbook book = excelEngine.Excel.Workbooks.Open(fileStream, ExcelOpenType.Automatic);
MemoryStream memoryStream = new MemoryStream();
book.SaveAs(memoryStream);
