Scrape data from html using js. For example: http://www.bangladesh.gov.bd/site/view/upazila-list/%E0%A6%89%E0%A6%AA%E0%A6%9C%E0%A7%87%E0%A6%B2%E0%A6%BE%E0%A6%B8%E0%A6%AE%E0%A7%82%E0%A6%B9

sample.js

var tables = document.getElementsByClassName('geotable');

var data = {};

for (var i = 0; i < tables.length; i++) {
   var rows = tables.item(i).rows; 
   
   var localArray = [];
   for (j = 0; j < rows.length; j++){
       var oCells = rows.item(j).cells;

       var ups = oCells.item(1).getElementsByTagName('a');

       var upsArray = [];
       
       for (k = 0; k < ups.length; k++){
            upsArray.push(ups.item(k).text);
       }
       localArray[oCells.item(0).innerText] = upsArray;
   }
   Object.assign(data,localArray);
}

console.log(JSON.stringify(data));
