Error with validators


i have a problem with validators in an excelfile.
If i create a list-item validator with aspose and save it. Then open it with Office-Excel an error occures.
I set the formula1 of the validation to „Yes,No“.

validation.Formula1 = @“Yes,No”;

With Aspose.Cells.dll in Version 18.10.x it worked well. Now with version 18.11 the error occures.

Thanks for the sample project with details.

After an initial test, I am able to reproduce the issue as you mentioned. I found when we create a file with list data validation (using the following sample code), MS Excel gives error when opening the output file into it. We simply set the formula1 of the validation to “Yes,No”:
Sample code:

Aspose.Cells.Workbook workbook = new Aspose.Cells.Workbook();
            Aspose.Cells.Worksheet worksheet = workbook.Worksheets[0];

            worksheet.Cells[0, 0].Value = "Teststring";

            Aspose.Cells.Cells cells = worksheet.Cells;
            Aspose.Cells.ValidationCollection validations = worksheet.Validations;

            Aspose.Cells.CellArea cellArea = new Aspose.Cells.CellArea();
            cellArea.StartRow = 0;
            cellArea.EndRow = 1048575;
            cellArea.StartColumn = 1;
            cellArea.EndColumn = 1;

            Aspose.Cells.Validation validation = validations[validations.Add(cellArea)];
            validation.ShowError = true;
            validation.AlertStyle = Aspose.Cells.ValidationAlertType.Stop;

            validation.Type = Aspose.Cells.ValidationType.List;
            validation.Formula1 = @"Yes,No";
            validation.ErrorTitle = "Error";

            workbook.Save("e:\\test2\\out1.xlsx", Aspose.Cells.SaveFormat.Xlsx);
