How can I get the JSON of interactive report without using index of rows to find the id ?

Here’s my code to create JSON :

let  json_array =  [];
   var grid =document.getElementsByClassName("CLASSNAME"); 
    var allRow =$(grid[1]).find('tr');
        for (j=1 ; j < allRow.length ; j++ ) {
               var row =$(allRow[j]).find('td');
               var ID = $(row[0]).find('a').attr('data_id');
               ///and others .......
   json_array.push(text)
                 }
json_array = '[' + json_array + ']'

as it seems if I or any users change the order of columns , the JSON’s data columns would be corrupted. Is there any ways to create the JSON without having problems like this and use something like data-id instead of row index ?
