Migration from PHPExcel

PhpSpreadsheet introduced many breaking changes by introducing namespaces and renaming some classes. To help you migrate existing project, a tool was written to replace all references to PHPExcel classes to their new names. But there are also manual changes that need to be done.

Automated tool

The tool is included in PhpSpreadsheet. It scans recursively all files and directories, starting from the current directory. Assuming it was installed with composer, it can be run like so:

cd /project/to/migrate/src
/project/to/migrate/vendor/phpoffice/phpspreadsheet/bin/migrate-from-phpexcel

Important The tool will irreversibly modify your sources, be sure to backup everything, and double check the result before committing.

Manual changes

In addition to automated changes, a few things need to be migrated manually.

Renamed readers and writers

When using IOFactory::createReader(), IOFactory::createWriter() and IOFactory::identify(), the reader/writer short names are used. Those were changed, along as their corresponding class, to remove ambiguity:

Before	After
'CSV'	'Csv'
'Excel2003XML'	'Xml'
'Excel2007'	'Xlsx'
'Excel5'	'Xls'
'Gnumeric'	'Gnumeric'
'HTML'	'Html'
'OOCalc'	'Ods'
'OpenDocument'	'Ods'
'PDF'	'Pdf'
'SYLK'	'Slk'

Simplified IOFactory

The following methods :

• PHPExcel_IOFactory::getSearchLocations()
• PHPExcel_IOFactory::setSearchLocations()
• PHPExcel_IOFactory::addSearchLocation()

were replaced by IOFactory::registerReader() and IOFactory::registerWriter(). That means IOFactory now relies on classes autoloading.

Before:

\PHPExcel_IOFactory::addSearchLocation($type, $location, $classname);

After:

\PhpOffice\PhpSpreadsheet\IOFactory::registerReader($type, $classname);

Removed deprecated things

Worksheet::duplicateStyleArray()

// Before
$worksheet->duplicateStyleArray($styles, $range, $advanced);

// After
$worksheet->getStyle($range)->applyFromArray($styles, $advanced);

DataType::dataTypeForValue()

// Before
DataType::dataTypeForValue($value);

// After
DefaultValueBinder::dataTypeForValue($value);

Conditional::getCondition()

// Before
$conditional->getCondition();

// After
$conditional->getConditions()[0];

Conditional::setCondition()

// Before
$conditional->setCondition($value);

// After
$conditional->setConditions($value);

Worksheet::getDefaultStyle()

// Before
$worksheet->getDefaultStyle();

// After
$worksheet->getParent()->getDefaultStyle();

Worksheet::setDefaultStyle()

// Before
$worksheet->setDefaultStyle($value);

// After
$worksheet->getParent()->getDefaultStyle()->applyFromArray([
    'font' => [
        'name' => $pValue->getFont()->getName(),
        'size' => $pValue->getFont()->getSize(),
    ],
]);

Worksheet::setSharedStyle()

// Before
$worksheet->setSharedStyle($sharedStyle, $range);

// After
$worksheet->duplicateStyle($sharedStyle, $range);

Worksheet::getSelectedCell()

// Before
$worksheet->getSelectedCell();

// After
$worksheet->getSelectedCells();

Writer\Xls::setTempDir()

// Before
$writer->setTempDir();

// After, there is no way to set temporary storage directory anymore

Autoloader

The class PHPExcel_Autoloader was removed entirely and is replaced by composer autoloading mechanism.

Writing PDF

PDF libraries must be installed via composer. And the following methods were removed and are replaced by IOFactory::registerWriter() instead:

• PHPExcel_Settings::getPdfRenderer()
• PHPExcel_Settings::setPdfRenderer()
• PHPExcel_Settings::getPdfRendererName()
• PHPExcel_Settings::setPdfRendererName()

Before:

\PHPExcel_Settings::setPdfRendererName(PHPExcel_Settings::PDF_RENDERER_MPDF);
\PHPExcel_Settings::setPdfRenderer($somePath);
$writer = \PHPExcel_IOFactory::createWriter($spreadsheet, 'PDF');

After:

$writer = \PhpOffice\PhpSpreadsheet\IOFactory::createWriter($spreadsheet, 'Mpdf');

// Or alternatively
\PhpOffice\PhpSpreadsheet\IOFactory::registerWriter('Pdf', \PhpOffice\PhpSpreadsheet\Writer\Pdf\Mpdf::class);
$writer = \PhpOffice\PhpSpreadsheet\IOFactory::createWriter($spreadsheet, 'Pdf');

// Or alternatively
$writer = new \PhpOffice\PhpSpreadsheet\Writer\Pdf\Mpdf($spreadsheet);

Rendering charts

When rendering charts for HTML or PDF outputs, the process was also simplified. And while JpGraph support is still available, it is unfortunately not up to date for latest PHP versions and it will generate various warnings.

If you rely on this feature, please consider contributing either patches to JpGraph or another IRenderer implementation (a good candidate might be CpChart).

Before:

$rendererName = \PHPExcel_Settings::CHART_RENDERER_JPGRAPH;
$rendererLibrary = 'jpgraph3.5.0b1/src/';
$rendererLibraryPath = '/php/libraries/Charts/' . $rendererLibrary;

\PHPExcel_Settings::setChartRenderer($rendererName, $rendererLibraryPath);

After:

Require the dependency via composer:

composer require jpgraph/jpgraph

And then:

Settings::setChartRenderer(\PhpOffice\PhpSpreadsheet\Chart\Renderer\JpGraph::class);

PclZip and ZipArchive

Support for PclZip were dropped in favor of the more complete and modern PHP extension ZipArchive. So the following were removed:

• PclZip
• PHPExcel_Settings::setZipClass()
• PHPExcel_Settings::getZipClass()
• PHPExcel_Shared_ZipArchive
• PHPExcel_Shared_ZipStreamWrapper

Cell caching

Cell caching was heavily refactored to leverage PSR-16. That means most classes related to that feature were removed:

• PHPExcel_CachedObjectStorage_APC
• PHPExcel_CachedObjectStorage_DiscISAM
• PHPExcel_CachedObjectStorage_ICache
• PHPExcel_CachedObjectStorage_Igbinary
• PHPExcel_CachedObjectStorage_Memcache
• PHPExcel_CachedObjectStorage_Memory
• PHPExcel_CachedObjectStorage_MemoryGZip
• PHPExcel_CachedObjectStorage_MemorySerialized
• PHPExcel_CachedObjectStorage_PHPTemp
• PHPExcel_CachedObjectStorage_SQLite
• PHPExcel_CachedObjectStorage_SQLite3
• PHPExcel_CachedObjectStorage_Wincache

In addition to that, \PhpOffice\PhpSpreadsheet::getCellCollection() was renamed to \PhpOffice\PhpSpreadsheet::getCoordinates() and \PhpOffice\PhpSpreadsheet::getCellCacheController() to \PhpOffice\PhpSpreadsheet::getCellCollection() for clarity.

Refer to the new documentation to see how to migrate.

Dropped conditionally returned cell

For all the following methods, it is no more possible to change the type of returned value. It always return the Worksheet and never the Cell or Rule:

• Worksheet::setCellValue()
• Worksheet::setCellValueByColumnAndRow()
• Worksheet::setCellValueExplicit()
• Worksheet::setCellValueExplicitByColumnAndRow()
• Worksheet::addRule()

Migration would be similar to:

// Before
$cell = $worksheet->setCellValue('A1', 'value', true);

// After
$cell = $worksheet->getCell('A1')->setValue('value');

Standardized keys for styling

Array keys used for styling have been standardized for a more coherent experience. It now uses the same wording and casing as the getter and setter:

// Before
$style = [
    'numberformat' => [
        'code' => NumberFormat::FORMAT_CURRENCY_EUR_SIMPLE,
    ],
    'font' => [
        'strike' => true,
        'superScript' => true,
        'subScript' => true,
    ],
    'alignment' => [
        'rotation' => 90,
        'readorder' => Alignment::READORDER_RTL,
        'wrap' => true,
    ],
    'borders' => [
        'diagonaldirection' => Borders::DIAGONAL_BOTH,
        'allborders' => [
            'style' => Border::BORDER_THIN,
        ],
    ],
    'fill' => [
        'type' => Fill::FILL_GRADIENT_LINEAR,
        'startcolor' => [
            'argb' => 'FFA0A0A0',
        ],
        'endcolor' => [
            'argb' => 'FFFFFFFF',
        ],
    ],
];

// After
$style = [
    'numberFormat' => [
        'formatCode' => NumberFormat::FORMAT_CURRENCY_EUR_SIMPLE,
    ],
    'font' => [
        'strikethrough' => true,
        'superscript' => true,
        'subscript' => true,
    ],
    'alignment' => [
        'textRotation' => 90,
        'readOrder' => Alignment::READORDER_RTL,
        'wrapText' => true,
    ],
    'borders' => [
        'diagonalDirection' => Borders::DIAGONAL_BOTH,
        'allBorders' => [
            'borderStyle' => Border::BORDER_THIN,
        ],
    ],
    'fill' => [
        'fillType' => Fill::FILL_GRADIENT_LINEAR,
        'startColor' => [
            'argb' => 'FFA0A0A0',
        ],
        'endColor' => [
            'argb' => 'FFFFFFFF',
        ],
    ],
];

Dedicated class to manipulate coordinates

Methods to manipulate coordinates that used to exists in PHPExcel_Cell were extracted to a dedicated new class \PhpOffice\PhpSpreadsheet\Cell\Coordinate. The methods are:

• absoluteCoordinate()
• absoluteReference()
• buildRange()
• columnIndexFromString()
• coordinateFromString()
• extractAllCellReferencesInRange()
• getRangeBoundaries()
• mergeRangesInCollection()
• rangeBoundaries()
• rangeDimension()
• splitRange()
• stringFromColumnIndex()

Column index based on 1

Column indexes are now based on 1. So column A is the index 1. This is consistent with rows starting at 1 and Excel function COLUMN() that returns 1 for column A. So the code must be adapted with something like:

// Before
$cell = $worksheet->getCellByColumnAndRow($column, $row);

for ($column = 0; $column < $max; $column++) {
    $worksheet->setCellValueByColumnAndRow($column, $row, 'value ' . $column);
}

// After
$cell = $worksheet->getCellByColumnAndRow($column + 1, $row);

for ($column = 1; $column <= $max; $column++) {
    $worksheet->setCellValueByColumnAndRow($column, $row, 'value ' . $column);
}

All the following methods are affected:

• PHPExcel_Worksheet::cellExistsByColumnAndRow()
• PHPExcel_Worksheet::freezePaneByColumnAndRow()
• PHPExcel_Worksheet::getCellByColumnAndRow()
• PHPExcel_Worksheet::getColumnDimensionByColumn()
• PHPExcel_Worksheet::getCommentByColumnAndRow()
• PHPExcel_Worksheet::getStyleByColumnAndRow()
• PHPExcel_Worksheet::insertNewColumnBeforeByIndex()
• PHPExcel_Worksheet::mergeCellsByColumnAndRow()
• PHPExcel_Worksheet::protectCellsByColumnAndRow()
• PHPExcel_Worksheet::removeColumnByIndex()
• PHPExcel_Worksheet::setAutoFilterByColumnAndRow()
• PHPExcel_Worksheet::setBreakByColumnAndRow()
• PHPExcel_Worksheet::setCellValueByColumnAndRow()
• PHPExcel_Worksheet::setCellValueExplicitByColumnAndRow()
• PHPExcel_Worksheet::setSelectedCellByColumnAndRow()
• PHPExcel_Worksheet::stringFromColumnIndex()
• PHPExcel_Worksheet::unmergeCellsByColumnAndRow()
• PHPExcel_Worksheet::unprotectCellsByColumnAndRow()
• PHPExcel_Worksheet_PageSetup::addPrintAreaByColumnAndRow()
• PHPExcel_Worksheet_PageSetup::setPrintAreaByColumnAndRow()

Removed default values

Default values for many methods were removed when it did not make sense. Typically, setter methods should not have default values. For a complete list of methods and their original default values, see that commit.
