Well, I think you may export your worksheet data to fill a datatable or array using Cells.ExportDataTable or Cells.ExportArray methods.
//You can open the excel file using Aspose.Cells.Workbook.Open() method, now export / fill a datatable based on the sheet data in the cells, finally use ADO.NET API or your own code to fill/update the SQL Server Database table(s) or other db tables for your need.//
Sample code:
Workbook wb = new Workbook(); wb.Open(“f:\test\MyExcelFile.xlsx”); Worksheet ws = wb.Worksheets[0]; int trows = ws.Cells.MaxDataRow; int tcols = ws.Cells.MaxDataColumn; DataTable dt = ws.Cells.ExportDataTable(0, 0,trows, tcols, true);
