Thanks for your posting and using Aspose.Cells.
At the moment, Aspose.Cells can only preserve macros during the conversion of Excel files and support to delete them. However, it cannot create, inject, modify or execute macros.
We only plan to create, manipulate or embed VB codes/macros in Q1, 2015. However, we cannot support to execute them.
We have also linked your thread to existing issue id to support this feature. Once, this feature is supported or if there is any update for you, we will let you know asap.
