What I have tried:

ConvertToCSV(objArray) {
    //var arr=['store_id','store_name','address1','address2','pincode','landmark','status_text']
    const newArray = objArray.map(o => {
      return { store_id: o.store_id, store_name: o.store_name, address: o.address1 +" "+ o.address2, pincode: o.pincode,landmark: o.landmark,status: o.status_text };
    });
    
    var array = typeof newArray != 'object' ? JSON.parse(newArray) : newArray;
    var str = '';
    var row = '';

   
    for (var index in newArray[0]) {
        //Now convert each value to string and comma-separated
        row += index + ',';
        
    }
    row = row.slice(0, -1);
    //append Label row with line break
    str += row + '\r\n';

    for (var i = 0; i < array.length; i++) {
      
        var line = '';
        for (var index in array[i]) {
            if (line != '') line += ','
            line += array[i][index];
        }
        str += line + '\r\n';
    }
    return str;
}
