Export button in a suitelet page

Hi,

I'm using a suitelet to display a list of custom records attached to sales order using the sales order internal id as a parameter.

Everything is working fine, but I want to add a button to let customer export the list as an excel or csv file.

Is this doable? if so, could you please tell how, add the code snippet or guide me to the support page that have more information?

Thanks in advance!
