How to search and replace a word in datatable rollCallback

I am using txt file to show the data into datatable, I edit the data on another screen and then I edit the file also, and the data which is edited, I concatenate a word "updated" with the original data in the file(for instance: 234updated), Now I want to search a data which contains word updated and replace it with blank and also highlight it with the color yellow. Here is my code

  $('#arrTableCustomer').DataTable({
            ajax: function(data, callback) {

                $.ajax({
                    url: "../Arr_Data_Files/<?php echo $clientName ?>_Arr2.txt",
                    dataType: 'json',
                    success: function(data) {
                        var array = [];
                        var array2 = [];
                        var array3 = [];
                        jQuery.each(data, function(index, value) {
                            for (i = 0; i < lengthArray2; i++) {
                                var array = [];
                                array.push(value[i][0]);
                                for (j = 1; j <= total; j++) {
                                    array.push(value[i][j]);
                                }
                                array2.push(array);
                            }
                        });
                        array3.push({
                            "data": array2
                        });
                        var obj = Object.assign({}, array3[0]);
                        callback(obj);
                    }
