title: how to enable export to csv in ag-grid
body: <p>I am using out of the box ag-grid , is there a feature on it for exporting to excel. So far i have not written any event code to export to csv. I was thinking that just like it's sort and filter features this is also implemented out of the box (like the context menu of highcharts as an example).</p>
  
  <p>So is there a grid option that I need to set to make it ready for exporting to to csv or excel</p>
  
  <p>thanks</p>
