How to export Subform Data from a record?

How can we export the subform data from a record?

Currently we can import data, but I found no way to export data from one record 




I need a simple button to export the current subform data to an excel file, why can we import subform data but cannot export it? 

I know about exporting all records, So dont suggest that, we dont want it 

I want to be able to export the current record that I have opened
