So i can see what I’ve got, not saving it.

How can I make visible excel object


Aspose.Excel is a non-UI component. To view the generated file, you should use MS Excel or ExcelViewer.

In a webform application, please use

excel.Save("book1.xls", SaveType.OpenInExcel, FileFormatType.Default, this.Response);

I’ve got one more question:

Aspose does it faster?
If yes - how much can I win usin’ it


MS Excel automation accesses content based on Range object while Aspose.Excel accesses content based on Cells and Cell object.

In your code, sure Aspose.Excel is much faster. But I don’t have data on the performance differences. You can write a simple program to evaluate it.
