Here I have my fetch function to retrieve data to put into an ag-grid datatable. The data are from Google Visualization API The problem here is that the Google API returns a constrained syntax like the picture on the right side. How can I retrieve this data to reassemble them in the structure as the picture on the left side to reuse it in ag-grid datatable?

json.table.rows.forEach((row)=>{
     console.log(row);
     row.c.forEach((cell)=> {
           const container1 =[cell].v;
           console.log(typeof container1);
         gridOptions.api.setRowData(container1); 
         
     })  
  });
