Spout is a PHP library to read and write spreadsheet files (CSV, XLSX and ODS), in a fast and scalable way.
Contrary to other file readers or writers, it is capable of processing very large files while keeping the memory usage really low (less than 3MB).

## Documentation

Full documentation can be found at [http://opensource.box.com/spout/](http://opensource.box.com/spout/).


## Requirements

* PHP version 5.4.0 or higher
* PHP extension `php_zip` enabled
* PHP extension `php_xmlreader` enabled


## Running tests

On the `master` branch, only unit and functional tests are included. The performance tests require very large files and have been excluded.
If you just want to check that everything is working as expected, executing the tests of the `master` branch is enough.

If you want to run performance tests, you will need to checkout the `perf-tests` branch. Multiple test suites can then be run, depending on the expected output:

* `phpunit` - runs the whole test suite (unit + functional + performance tests)
* `phpunit --exclude-group perf-tests` - only runs the unit and functional tests
* `phpunit --group perf-tests` - only runs the performance tests

For information, the performance tests take about 30 minutes to run (processing 1 million rows files is not a quick thing).
