Hello, Thomas,

Currently, RadSpreadProcessing provides support for the XLSM format (macro-enabled spreadsheet created by Microsoft Excel). However, macros are only preserved during import and export. They cannot be executed or changed in the code with the current implementation.

The public feedback portal allows us to be better aware of the needs of our customers by reviewing all requests and measuring their popularity. Our roadmap and priorities depend largely on the business value and customers' demand for specific features, and we take into account the most popular requests when planning our future development efforts. 

We are doing everything in our power to answer customer requests and needs by resolving these tasks as fast as possible, but some receive less attention than others, which is why they can sometimes be delayed, just like this. 

I can suggest you to cast your vote for them in order to increase their priority in our backlog and to make sure you are keeping track of it by subscribing if you haven't already. 

Regarding the charts inside a worksheet, you can also have a look at the Using Charts article summarizing the currently available functionality that may be applicable for the scenario you need to cover. If you have any further questions, you may consider submitting a support ticket from your Telerik account. Thus, the support engineers would provide further assistance.

Regards,
Dess | Tech Support Engineer, Principal
