Dear Team Aspose:
Hi,
Thank you for considering Aspose.
You may use Workbook.Combine API to combine / merge multiple excel workbooks into one workbook. Please see the following documentation article for further details and sample code.

Thank You & Best Regards,
Many Thanks!!
See our new/updated document on the feature for your reference:
Combine workbooks
Also, we recommend to upgrade to newer Aspose.Cells for .NET, which has many useful features and other enhancements. The following sample code exhibits on how to combine two workbooks into one file:
e.g.
Sample code:
Workbook SourceBook1 = new Workbook("Book1.xlsx");
// Define the second source book.
// Open the second excel file.
Workbook SourceBook2 = new Workbook("Book2.xlsx");
// Combining the two workbooks
SourceBook1.Combine(SourceBook2);
// Save the target book file.
SourceBook1.Save("combinedBook.xlsx");
