How to set the property label dynamic in sap gateway

Currently, we are facing the issue related to export the UI5 table content into an excel by accessing back-end gateway serivce by adding "format=xlsx". For now, the text for column is fixed and inherited from property label maintained in back-end. We want to set the property label dynamically based on certain template so that the excel column text can be changed correspondingly.

Does anyone have any solution for this issue?

Thanks in advance.

Best Regards,

Zac
