I have resaved the workbook (.xls → .xls) with Aspose.Cells and the result is opened in Protected View by MS Excel. The original workbook opens without any warnings.
I attached the workbook.
Code sample:
var wb = new …...Protected View after resaving Aspose.Cells Product Family cells-net...workbook (.xls → .xls) with Aspose.Cells and the result is opened...
