EXCEL Export in 3.8

If It try to export all products I receive the following error.

Validation of G2 failed: Formula1 cannot be empty

System.InvalidOperationException: Validation of G2 failed: Formula1 cannot be empty at OfficeOpenXml.DataValidation.ExcelDataValidationWithFormula`1.Validate() at OfficeOpenXml.DataValidation.ExcelDataValidationCollection.ValidateAll() at OfficeOpenXml.ExcelWorkbook.ValidateDataValidations() at OfficeOpenXml.ExcelWorkbook.Save() at OfficeOpenXml.ExcelPackage.Save() at Nop.Services.ExportImport.ExportManager.ExportProductsToXlsxWithAttributes(PropertyByName`1[] properties, IEnumerable`1 itemsToExport) at Nop.Admin.Controllers.ProductController.ExportExcelAll(ProductListModel model)

Hi,

It's the bug when you don't have any vendors. Please create at least one in order to make it work

Or you can switch to "Basic" mode on the product details page (and disable vendors on product editor settings popup page)

Fixed. Please see this commit. Thanks a lot for reporting!
