Call a Custom Function Before Excel Download

Antony Rayan

Hi, I have n rows and I want to export the data in excel or csv or PDF.
When I click these buttons, I want to call a custom function to perform some action with database.
After performing with database, then it should download the data in selected format.
How to do?
