Undesirable rounding off of numbers in generated PHPexcel - mysql

Question

I am generating a downloadable excel file from mysql database using phpexcel. In that, there is a field having 18 digit number, which in the mysql, it is defined as Bigint. The number is defined as a hyperlink in the code. Now, there is the following problem -
The last 4 digits of the number hyperlink are displayed as 0000 although on clicking the number hyperlink, it is opening correctly. Example 860814069447613475 is shown as 860814069447610000 in the generated excel
Here is my code -
$objPHPExcel->getActiveSheet()
->getStyle('A'.(string)$n)
->getNumberFormat()
->setFormatCode(
PHPExcel_Style_NumberFormat::FORMAT_NUMBER
);
$n = 2;
while ($row = mysqli_fetch_array($result)){
$objPHPExcel->getActiveSheet()->setCellValue('A'.(string)$n,
$row['t_id']);
$objPHPExcel->getActiveSheet()->setCellValue('B'.(string)$n,
$row['t_text']);
$objPHPExcel->getActiveSheet()->setCellValue('C'.(string)$n,
$row['user_name']);
$objPHPExcel->getActiveSheet()->setCellValue('D'.(string)$n,
$row['description']);
$objPHPExcel->getActiveSheet()->setCellValue('E'.(string)$n
,$row['time']);
$objPHPExcel->getActiveSheet()->setCellValue('F'.(string)$n,
$row['place']);
$objPHPExcel->getActiveSheet()->getStyle("A$n:F$n")->getAlignment()-
>setWrapText(true);
$objPHPExcel->getActiveSheet()
->getCell('A'.(string)$n)
->getHyperlink()
->setUrl('http://t.com/'.$row['user_name'].'/status/' . $row['t_id']);
// Config
$link_style_array = [
'font' => [
'color' => ['rgb' => '0000FF'],
'underline' => 'single'
]
];
// Set it!
$objPHPExcel->getActiveSheet()->getStyle('A'.(string)$n)->applyFromArray($link_style_array);
$n++;
}

Answer 1

Found code which worked for me -
setCellValueExplicit('A'.(string)$n, $row['t_id'],
PHPExcel_Cell_DataType::TYPE_STRING);
