How to represent datasubset data in Excel sheet

Hi 

I have a Data got from a view with selection and filtering and displaying in a Grid. Now i need to have button in that interface to call export to excel. This interface is a report in Tempo. I am not able to use 

a!exportDataStoreEntityToExcel function because i have a data, again i cannot configure to get data, because it is a large set of data, getting time out from Database. But i have already tuned performance of that query in separate expression rule.

Please let me know how to pass datasubset to excel for 19.2 version
