You can create unique names of SheetName
using number or date. Please refer to the code snippet below:
sender, EventArgs e)
exporter.ExportFormat = SpreadExportFormat.Xlsx;
exporter.FileExportMode = FileExportMode.NewSheetInExistingFile;
Another suggestion is to set the FileExportMode
property to CreateOrOverrideFile
which will override the specified file and it is not necessary to create unique name of sheet each time.
Hope this will help you. Let me know if you have any other questions.
