Easily manipulate PhpSpreadsheet, OpenSpout and League CSV

Why use this ?

Importing/exporting csv data is a very common task in web development. While it's a very efficient format, it's also somewhat difficult for end users that are used to Excel. This is why you often end up accepting also xlsx format as a import/export target.

Ideally, importing single sheets of csv or excel should be just a matter of changing an adapter. Thankfully, this package does just this :-)

Supported packages

OpenSpout: fast csv and excel import/export https://github.com/openspout/openspout

League CSV: very fast csv import/export. Can read streams. https://github.com/thephpleague/csv

PhpSpreadsheet: slow excel (xls and xlsx) and csv import/export, but more features https://github.com/PHPOffice/PhpSpreadsheet

Native php: very fast csv import/export, but limited features. Can read/output streams.

SimpleXLSX: very fast excel import/export https://github.com/shuchkin/simplexlsx https://github.com/shuchkin/simplexlsxgen

This package will prioritize installed library, by order of performance. You can also pick your preferred adapter for each format like this:

SpreadCompat::$preferredCsvAdapter = SpreadCompat::NATIVE; // our native csv adapter is the fastest
SpreadCompat::$preferredXlsxAdapter = SpreadCompat::NATIVE; // our native xlsx adapter is the fastest

Using the facade

While you can use individual adapters, it's very likely you don't want to bother too much how your files are read and written. This package provides a simple facade with static methods in order to read and write files.

Please note that read methods return a Generator. If you want an array, you need to use iterator_to_array.

$data = iterator_to_array(SpreadCompat::read('myfile.csv'));

// or
foreach(SpreadCompat::read('myfile.csv') as $row) {
    // Do something
}

Output to browser

This package includes a simple way to leverage output to browser type of functionnality.

Some adapters allow you to stream directly the response.

SpreadCompat::output('myfile.csv');
exit();

Configure

Using named arguments

This package accepts options using ...opts, this means you can freely use named arguments or pass an array.

$data = iterator_to_array(SpreadCompat::read('myfile.csv', assoc: true));

// or
$data = iterator_to_array(SpreadCompat::read('myfile.csv', ...$opts));

Using options object

You can also use the Options class that regroups all available options for all adapters. Unsupported options are ignored.

$options = new Options();
$options->separator = ";";
$data = iterator_to_array(SpreadCompat::read('myfile.csv', $options));

Worksheets

This package supports only 1 worksheet, as it is meant to be able to replace csv by xlsx or vice versa

Benchmarks

Since we can compare our solutions, there is a built in bench.php script that give the following results on my machine

Reading a file with 5000 rows:

Results for csv
LeKoala\SpreadCompat\Csv\Native : 0.0079
LeKoala\SpreadCompat\Csv\League : 0.0304
LeKoala\SpreadCompat\Csv\OpenSpout : 0.0924
LeKoala\SpreadCompat\Csv\PhpSpreadsheet : 3.9437

Results for xlsx
LeKoala\SpreadCompat\Xlsx\Native : 0.0636
LeKoala\SpreadCompat\Xlsx\Simple : 0.1585
LeKoala\SpreadCompat\Xlsx\PhpSpreadsheet : 0.7502
LeKoala\SpreadCompat\Xlsx\OpenSpout : 0.8748

Write a file with 2500 rows:

Results for csv
LeKoala\SpreadCompat\Csv\Native : 0.0053
LeKoala\SpreadCompat\Csv\League : 0.0143
LeKoala\SpreadCompat\Csv\OpenSpout : 0.0428
LeKoala\SpreadCompat\Csv\PhpSpreadsheet : 0.3491

Results for xlsx
LeKoala\SpreadCompat\Xlsx\Native : 0.0263
LeKoala\SpreadCompat\Xlsx\Simple : 0.0793
LeKoala\SpreadCompat\Xlsx\OpenSpout : 0.2621
LeKoala\SpreadCompat\Xlsx\PhpSpreadsheet : 0.6322

For simple imports/exports, it's very clear that using the Native adapter is the fastest. These are not enabled by default since they might lack some compatibility feature you may require.

Stop wasting cpu cycles right now and please use the most efficient adapter :-)
