For the excel, this function will add a new rows at the top of document:

customize: function (xlsx) {
                var sheet = xlsx.xl.worksheets['sheet1.xml'];
                var numrows = 3;
                var clR = $('row', sheet);

                //update Row
                clR.each(function () {
                    var attr = $(this).attr('r');
                    var ind = parseInt(attr);
                    ind = ind + numrows;
                    $(this).attr("r",ind);
                });

                // Create row before data
                $('row c ', sheet).each(function () {
                    var attr = $(this).attr('r');
                    var pre = attr.substring(0, 1);
                    var ind = parseInt(attr.substring(1, attr.length));
                    ind = ind + numrows;
                    $(this).attr("r", pre + ind);
                });

                function Addrow(index,data) {
                    msg='<row r="'+index+'">'
                    for(i=0;i<data.length;i++){
                        var key=data[i].key;
                        var value=data[i].value;
                        msg += '<c t="inlineStr" r="' + key + index + '">';
                        msg += '<is>';
                        msg +=  '<t>'+value+'</t>';
                        msg+=  '</is>';
                        msg+='</c>';
                    }
                    msg += '</row>';
                    return msg;
                }


                //insert
                var r1 = Addrow(1, [{ key: 'A', value: '' }, { key: 'B', value: '' }]);
                var r2 = Addrow(2, [{ key: 'A', value: '' }, { key: 'B', value: '' }]);
                var r3 = Addrow(3, [{ key: 'A', value: '' }, { key: 'B', value: '' }]);

                sheet.childNodes[0].childNodes[1].innerHTML = r1 + r2+ r3+ sheet.childNodes[0].childNodes[1].innerHTML;
            }

For CSV:

customize: function(doc){
                return "Your text" + doc;
            }

For the others exports you will need to put a message parameter like this:

{
            extend: 'print',
            message: "Your text"
        },
