Export datagrid data to .xls

Hello there, so I have a dynamic datagrid in a details page which my client want’s to be exportable so he can have it in .xls, send over emails or whatever.

The workflow goes like this:

There is a page with a list of “Campaigns” and each campaign has a button which leads to a details page of the campaign, in this detailed page I have a datagrid component which shows all the answers from different users to the selected campaign (the component is binded to all the answers in my database and then filtered in weweb to the selected campaign). This data is shown as follows and my client is requesting me to add a “Download” button, how can I do that?
