Spout is a PHP library to read and write spreadsheet files (CSV, XLSX and ODS), in a fast and scalable way.
Unlike 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 [https://opensource.box.com/spout/](https://opensource.box.com/spout/).
## Requirements
* PHP version 7.2 or higher
* PHP extension `php_zip` enabled
* PHP extension `php_xmlreader` enabled
## Upgrade guide
Version 3 introduced new functionality but also some breaking changes. If you want to upgrade your Spout codebase from version 2 please consult the [Upgrade guide](UPGRADE-3.0.md).
## Running tests
The `master` branch includes unit, functional and performance tests.
If you just want to check that everything is working as expected, executing the unit and functional tests is enough.
* `phpunit` - runs unit and functional tests
* `phpunit --group perf-tests` - only runs the performance tests
For information, the performance tests take about 10 minutes to run (processing 1 million rows files is not a quick thing).
> Performance tests status: [](https://travis-ci.org/box/spout)
