PHP_XLSXWriter

This library is designed to be lightweight, and have relatively low memory usage.

It is designed to output an Excel spreadsheet in with (Office 2007+) xlsx format, with just basic features supported:

  • supports PHP 5.2.1+
  • takes UTF-8 encoded input
  • multiple worksheets
  • supports currency/date/numeric cell formatting, simple formulas

Give this library a try, if you find yourself running out of memory writing spreadsheets with PHPExcel.

Simple PHP CLI example:

$data = array(
    array('year','month','amount'),
    array('2003','1','220'),
    array('2003','2','153.5'),
);

$writer = new XLSXWriter();
$writer->writeSheet($data);
$writer->writeToFile('output.xlsx');

Multiple Sheets:

$data1 = array(  
     array('5','3'),
     array('1','6'),
);
$data2 = array(  
     array('2','7','9'),
     array('4','8','0'),
);

$writer = new XLSXWriter();
$writer->setAuthor('Doc Author');
$writer->writeSheet($data1,'Sheet1');
$writer->writeSheet($data2,'Sheet2');
echo $writer->writeToString();

Simple/Advanced Cell Formats:

//simple formats: date, datetime, integer, dollar, euro, string
$header = array(
  'created'=>'date',
  'product_id'=>'integer',
  'quantity'=>'#,##0',
  'amount'=>'dollar',
  'description'=>'string',
  'tax'=>'[$$-1009]#,##0.00;[RED]-[$$-1009]#,##0.00',
);
$data = array(
    array('2015-01-01',873,1,'44.00','misc','=D2*0.05'),
    array('2015-01-12',324,2,'88.00','none','=D3*0.05'),
);

$writer = new XLSXWriter();
$writer->writeSheet($data,'Sheet1', $header);
$writer->writeToFile('example.xlsx');

Load test with 50000 rows: (runs fast, with low memory usage)

include_once("xlsxwriter.class.php");
$header = array('c1'=>'string','c2'=>'string','c3'=>'string','c4'=>'string');
$writer = new XLSXWriter();
$writer->writeSheetHeader('Sheet1', $header );//optional
for($i=0; $i<50000; $i++)
{
    $writer->writeSheetRow('Sheet1', array(rand()%10000,rand()%10000,rand()%10000,rand()%10000) );
}
$writer->writeToFile('output.xlsx');
echo '#'.floor((memory_get_peak_usage())/1024/1024)."MB"."\n";
