PHP_XLSXWriter

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

It is designed to output an Excel compatible spreadsheet in (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
  • supports basic cell styling
  • supports writing huge 100K+ row spreadsheets

Never run out of memory with PHPExcel again.

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');

Simple/Advanced Cell Formats:

$header = array(
  'created'=>'date',
  'product_id'=>'integer',
  'quantity'=>'#,##0',
  'amount'=>'price',
  '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->writeSheetHeader('Sheet1', $header );
foreach($data as $row)
	$writer->writeSheetRow('Sheet1', $row );
$writer->writeToFile('example.xlsx');

50000 rows: (1.4s, 0MB memory usage)

include_once("xlsxwriter.class.php");
$writer = new XLSXWriter();
$writer->writeSheetHeader('Sheet1', array('c1'=>'integer','c2'=>'integer','c3'=>'integer','c4'=>'integer') );
for($i=0; $i<50000; $i++)
{
    $writer->writeSheetRow('Sheet1', array($i, $i+1, $i+2, $i+3) );
}
$writer->writeToFile('huge.xlsx');
echo '#'.floor((memory_get_peak_usage())/1024/1024)."MB"."\n";
rows time memory
50000 1.4s 0MB
100000 2.7s 0MB
150000 4.1s 0MB
200000 5.7s 0MB
