PHP fails to download Excel file that is generated by PHP Excel - php

I want to download excel file (instead of saving it). Since I want to export HTML table I am using PHPExcel_reader_HTML to read contents of HTML table. Excel file is created perfectly when I want to save it but when I want to download it, nothing happens. Does someone knows where's the problem?
Code:
<?php
// Load the table view into a variable
$html = $_POST["table"];
require_once('php/PHPExcel/Classes/PHPExcel.php');
// Put the html into a temporary file
$objPHPExcel = new PHPExcel();
$tmpfile = time().'.html';
file_put_contents($tmpfile, $html);
// Read the contents of the file into PHPExcel Reader class
$reader = new PHPExcel_Reader_HTML;
$content = $reader->load($tmpfile);
// Pass to writer and output as needed
$objWriter = PHPExcel_IOFactory::createWriter($content, 'Excel2007');
header("Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet");
header("Content-Disposition: attachment; filename=\"results.xlsx\"");
header("Cache-Control: max-age=0");
$objWriter->save("php://output");
ob_clean();
// Delete temporary file
unlink($tmpfile);
?>

Create Excel from HTML using PHPExcel

I am using HTML code in a variable and I do not know how can I pass to generate Excel using PHPExcel.
I am able to generate Excel with load HTML file but if I want use HTML in a variable then I am confused. Please give me an idea on how to implement this.
My sample code is below.
<?php
require_once 'PHPExcel.php';
require_once 'PHPExcel/IOFactory.php';
$objPHPExcel = new PHPExcel();
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment;filename="name_of_file.xls"');
header('Cache-Control: max-age=0');
$html ='<table><tr><td><font color="blue">Hello</font></td><td><font style="color: blue;">Rest</font></td></tr><tr><td><font style="color: green;">Next</font></td><td><font style="color: Yellow;">Back</font></td></tr></table>';
$wizard = new PHPExcel_Helper_HTML;
$richText = $wizard->buildTextRun($html);
$objPHPExcel->setActiveSheetIndex(0);
$objPHPExcel->getActiveSheet()->setCellValue('A1', $richText);
$objPHPExcel->getActiveSheet()->setTitle('Sheet 1');
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
$objWriter->save('php://output', 'w');
?>
When I am using it in variable then its showing all in column vise but I want that all should come new row vise.

Error : the file format or file extension is not valid. verify that the file has not been corrupted

i want to use PHPSpreadsheet library in my project to export data to excel the file exported but when i try to open the file this error display: excel cannot open the file because the file format or file extension is not valid. verify that the file has not been corrupted
Note: i use MVC in my project
so the code in controller as the following:
protected function Excel($view, $variables = [])
{
require_once PATH_LIBRARY_FOLDER.'PhpSpreadsheet\vendor\autoload.php';
ob_start();
// Note: make new Spreadsheet object
$spreadsheet = new Spreadsheet();
// Note: get current active sheet (frist sheet)
$sheet = $spreadsheet->getActiveSheet();
$sheet->setCellValue('A1', 'Hello World !');
extract($variables);
include($this->viewPath.$view.'.php');
// Note: set the header to define it is excel file
header("Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet");
// Note: set the header to define excel file name
header("Content-Disposition: attachment;filename=\"filename.xlsx\"");
header("Cache-Control: max-age=0");
// Note: create IOFactory object
$writer = IOFactory::createWriter($spreadsheet, 'xlsx');
ob_get_clean();
$writer->save('php:://output');
exit();
}
when i open the file as a text i found this error:
Fatal error: Uncaught PhpOffice\PhpSpreadsheet\Writer\Exception: Could not open php:://output for writing. in C:\xampp\htdocs\GL_App\Library\PhpSpreadsheet\vendor\phpoffice\phpspreadsheet\src\PhpSpreadsheet\Writer\Xlsx.php:218
I have the same problem,My solution here . Just put code below :
ob_end_clean();
Code:
ob_end_clean();
header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
header('Content-Disposition: attachment;filename="'. $filename );
header('Cache-Control: max-age=0');
$writer->save('php://output'); // download file
Change this line of code
$writer->save('php:://output');
to
$writer->save('php://output');
It should work. Also, how do you pass data to excel sheet? It's possible that you have corrupt data.
Please, insert this in your code after autoload.php
use PhpOffice\PhpSpreadsheet\Spreadsheet;
use PhpOffice\PhpSpreadsheet\Writer\Xlsx;

Print raw html to xls file in php

I am trying to create a xls file in php. And I am making a string in html format lets say <table><tr><td>Cell 1</td><td>Cell 2</td></tr></table> and want to print in xls file as it is. but My problem is that when I try to print in xls file its getting render. but I want raw html string without rendered in xls file.
Here is my code:-
<?php
$file="demo.xls";
$test="<table><tr><td>Cell 1</td><td>Cell 2</td></tr></table>";
header('Content-type: application/excel');
header("Content-Disposition: attachment; filename=$file");
echo $test;
?>php
You can also use a service called DocRaptor which does html to excel conversion. http://docraptor.com/ , Multiple language supported
Or You can use the below code to download the file in Excel but first you have to download the PHPExcel class files and include like below .
require_once "excel/Classes/PHPExcel.php";
$objTpl = new PHPExcel();
$l=0;
$row_num = 1;
$objTpl->getActiveSheet()->getDefaultStyle()->getFont()->setName('Calibri');
$objTpl->getActiveSheet()->getDefaultStyle()->getFont()->setSize(10);
$objTpl->getActiveSheet()->getStyle('A1')->getFont()->setBold(true);
$objTpl->getActiveSheet()->duplicateStyle($objTpl->getActiveSheet()->getStyle('A1'), 'B1:Z1');
$objTpl->getActiveSheet()->getStyle('A1:Z1')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
// you can use loop over here remember to set $row_num = 2 if using loop and increment it inside $row_num++
$objTpl->getActiveSheet()->setCellValueByColumnAndRow($l++,$row_num, 'Cell 1');
$objTpl->getActiveSheet()->setCellValueByColumnAndRow($l++,$row_num, 'Cell 2');
$filename='some_file.xls'; //just some random filename
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment;filename="'.$filename.'"');
header('Cache-Control: max-age=0');
$objWriter = PHPExcel_IOFactory::createWriter($objTpl, 'Excel5'); //downloadable file is in Excel 2003 format (.xls)
$objWriter->save('php://output'); //send it to user, of course you can save it to disk also!
exit; //done.. exiting!
There is a way by either writing html in file or comma separated text
With HTML
$xlsx_file = $pathinfo['dirname']."/".$pathinfo['filename'].".xlsx" ;
$fh = fopen($xlsx_file, 'w+');<br>
fwrite($fh, $table); // your table <br>
fclose($fh);<br>
with array or string of csv
$data = '"Name"t"City"t"Country"' . "n";<br>
$data .= '"Ashok"t"New Delhi"t"India"' . "n";<br>
$data .= '"Krishna"t"Bangalore"t"India"' . "n";<br>
$f = fopen('data.xls' , 'wb');<br>
fwrite($f , $data );<br>
fclose($f);<br>
this is temporary solution but if you want full set of options you go for PHP Excel as suggested by others

PHPExcel Export HTML String is Exporting Entire HTML Page

I have a table on an html page that I need to export. I have searched other examples on here but nothing that works for me.
Here is what I have.
$filename = "DownloadReport";
//$table = dbGrid($q);
$table = "<div><table><tbody><tr><td>cars</td><td>cars</td><td>cars</td></tr></tbody></table></div>";
$tmpfile = tempnam(sys_get_temp_dir(), 'html');
file_put_contents($tmpfile, $table);
$excelHTMLReader = PHPExcel_IOFactory::createReader('HTML');
$objPHPExcel = $excelHTMLReader->load($tmpfile);
$objPHPExcel->getActiveSheet()->setTitle('anynameyouwant');
unlink($tmpfile);
header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
header('Content-Disposition: attachment;filename="' . $filename . '-' . date("y.m.d") . '.xlsx"');
header('Cache-Control: max-age=0');
$writer = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
$writer->save('php://output');
exit;
It properly downloads the file. But for some reason its saving my entire html page with javascript and css files missing. I only need to export the table string. I have a dbGrid function to create my table but for testing I have a simple table string.
How can I export just that table string, not my entire html page.

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');
