PhpSpreadsheet corrupted xlsx file - php

I have issue when trying to download xlsx file. It works just fine when i test it locally, but when i upload it to production server, file gets corrupted.
this is the file output:
this is code im using:
<?php
require 'conn.php';
require 'vendor/autoload.php';
use PhpOffice\PhpSpreadsheet\Spreadsheet;
use PhpOffice\PhpSpreadsheet\Writer\Xlsx;
use PhpOffice\PhpSpreadsheet\IOFactory;
$spreadsheet = new Spreadsheet();
$sheet = $spreadsheet->getActiveSheet();
$sheet->setCellValue('A1', '#');
$sheet->setCellValue('B1', 'First');
$sheet->setCellValue('C1', 'Last');
$sheet->setCellValue('D1', 'Handle');
header('Content-Type: application/vnd.openxmlformats-
officedocument.spreadsheetml.sheet');
header('Content-Disposition: attachment;filename="text.xlsx"');
header('Cache-Control: max-age=0');
$writer = IOFactory::createWriter($spreadsheet, 'Xlsx');
$writer->save('php://output');
die;
i tried changing header to, it did not help:
header('Content-type: application/vnd.ms-excel');

I think that will be ok if you add cleaning of the output buffer before you call createWriter static method.
ob_end_clean();
$writer = IOFactory::createWriter($spreadsheet, 'Xlsx');
$writer->save('php://output');

I had the same symptom and it was because the webserver continued to output things after doing
$writer->save('php://output');
In my case it was feasible to just do a die() after it and the problem's gone.
Maybe it can save somebody a little time.

I had the same problem and ob_end_clean();solved my problem also. The last lines are below.
ob_end_clean();
$writer=new Xlsx($spreadsheet);
header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
header('Content-Disposition: attachment; filename="'.urlencode($file_name).'"');
$writer->save('php://output');

Creating Excel file using PhpSpreadsheet with default data using Laravel 5.5

I am trying to download excel file with pre-populated data using PhpSpreadsheet in laravel. But I am got empty file downloaded.Here`s my code.
use PhpOffice\PhpSpreadsheet\Spreadsheet;
use PhpOffice\PhpSpreadsheet\Writer\Xlsx;
$spreadsheet = new Spreadsheet();
$sheet = $spreadsheet->getActiveSheet();
$sheet->setCellValue('B1','testing');
$writer = new Xlsx($spreadsheet);
$filename = 'tessa';
header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
header('Content-Disposition: attachment;filename="'. $filename .'.Xlsx"');
header('Cache-Control: max-age=0');
$writer->save($filename);
I tried dd($sheet) Here how it looks,it contains my data;
The file downloaded but empty file.Can any one tell me how to solve the issue?
You don't really need to set those headers. But if you must, edit filename to:
$filename = 'tessa.xlsx';
You need to change
$writer->save($filename);
to:
$writer->save('php://output');

PHPExcel excel2007 php output with charts

I use latest PHPExcel library for creating .xls, .xlsx files. When i try to output created file like this:
ob_end_clean();
$file = 'test.xls';
header('Content-Type: application/vnd.ms-excel; charset=UTF-8');
header('Content-Disposition: attachment; filename="'.$file.'"');
header('Cache-Control: max-age=0');
header('Cache-Control: max-age=1');
$objPHPWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
$objPHPWriter->setIncludeCharts(TRUE);
$objPHPWriter->save('php://output');
exit;
everything is fine until I try to create and output any charts. So i changed my code according to example:
ob_end_clean();
$objPHPWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
$objPHPWriter->setIncludeCharts(TRUE);
$objPHPWriter->save(str_replace('.php', '.xlsx', __FILE__));
exit;
This is working, but the file is not downloaded. So i modified code to output created file:
ob_end_clean();
$file = 'test.xlsx';
header('Content-Type: Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet; charset=UTF-8');
header('Content-Disposition: attachment; filename="'.$file.'"');
header('Cache-Control: max-age=0');
header('Cache-Control: max-age=1');
$objPHPWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
$objPHPWriter->setIncludeCharts(TRUE);
$objPHPWriter->save('php://output');
exit;
And this is not working, ends up with ERR_INVALID_RESPONSE.
Also when i store excel file with charts with second code block, it's not compatibile with MS Excel 2016. It says the file is corrupted and the data were replaced or deleted. What am I missing? Thanks a lot.
I figured out one simple solution, first step is to store created .xlsx file, second is to download file with header("Location:"). Redundant files are deleted with array_map function.
array_map('unlink', glob( __DIR__."/*.xlsx"));
$file = 'test.xlsx';
$objPHPWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
$objPHPWriter->setIncludeCharts(TRUE);
$objPHPWriter->save($file);
header("Location: $file");

PHPExcel unknown characters

I've followed some tutorials and saw some people with same issue but I can't figure out how to put this working on my project.
Btw, I'm using CodeIgniter framework and I have Excel 2007 in my computer.
public function exportExcel(){
require(APPPATH . 'libraries/toExcel/PHPExcel.php');
$objPHPExcel = new PHPExcel();
$objPHPExcel->setActiveSheetIndex(0)
->setCellValue('A1', 'Hello');
// Rename worksheet
$objPHPExcel->getActiveSheet()->setTitle('Simple');
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
header('Content-Type: application/vnd.ms-excel; charset=utf-8');
header('Content-Disposition: attachment; filename=01simple.xls');
header('Cache-Control: max-age=0');
$objWriter->save('php://output');
exit;
}
This is my code just for testings. Whenever I download the file generated by that function and try to open it is this what I get:
And when I click "Yes" I receive this:
Solved.
ob_end_clean();
ob_start();
$objWriter->save('php://output');
All php_excel changed Unknown Creator worksheet.
directory application/third_party/phpexcel/PHPExcel/DocumentProperties.php
changed line 43;
private $creator = 'Unknown Creator'; changed ↓
private $creator = 'your name';

PHPExcel - Templates work but mine are corrupt

I am trying to write data to a template and download it.
If i use the sample files as a template, it works but once I use my own it says its corrupt.
Any thoughts?
My code is:
<?php
require_once 'PHPExcel.php';
// Create new PHPExcel object
$fileName = '31docproperties.xlsx'; //location of template for PID type
$fileType = 'Excel2007';
$objReader = PHPExcel_IOFactory::createReader($fileType);
$objPHPExcel = $objReader->load($fileName);
$objPHPExcel->setActiveSheetIndex(0)->setCellValue('B4', 'Test Data');
// Redirect output to a client’s web browser (Excel2007)
header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
header('Content-Disposition: attachment;filename="01simple.xlsx"');
header('Cache-Control: max-age=0');
ob_end_clean();
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
$objWriter->save('php://output');
exit;
?>

PHPExcel is not generating correct xls file

I am using PHPExcel in my project to generate a xls file of data coming from the database. I have downloaded the library of PHPExcel and using it in my PHP class as give below :
Class name : A.class.php
Path : inside a folder named "inc";
PHPExcel Lib folder : inside "inc" and relative to A.class.php
class A{
// code stuff
public function phpexcelgenerate()
{
require_once 'PHPExcel_1.7.9_doc/Classes/PHPExcel.php';
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment;filename="sam.xlsx"');
header('Cache-Control: max-age=0');
$objPHPExcel = new PHPExcel;
$objPHPExcel->setActiveSheetIndex(0);
$objPHPExcel->getActiveSheet()->SetCellValue('A1', "12");
$writer = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
// This line will force the file to download
$writer->save();
}
// code stuff
}
This code is generating a xls file but that file is fully empty. I am thinking that I have included the files of PHPExcel in a wrong way in PHP classes. Could anyone tell me where I am doing wrong OR an example how can I do the same ?
You need to pass a filename to the save() method. Then read the contents of that files and echo to the browser.
$writer = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
$writer->save("excel.xls");
readfile("excel.xls");
first of all you need to read the file:
// Read the file
$objReader = PHPExcel_IOFactory::createReader(Excel5);
$objPHPExcel = $objReader->load($fileName);
now get the data from db:
//get data
$details = $this->main_model->get_details()->row();
then assign the data to correct cells:
$objPHPExcel->getActiveSheet()->setCellValue('A'.$row, $i);
$objPHPExcel->getActiveSheet()->setCellValue('B'.$row, $rec->eType);
at the end write the new file:
header('Content-Type: application/vnd.ms-excel'); //mime type
header('Content-Disposition: attachment;filename="'.$filename.'"'); //tell browser what's the file name
header('Cache-Control: max-age=0'); //no cache
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
//force user to download the Excel file without writing it to server's HD
$objWriter->save('php://output');
