OpenSpout is a community driven fork of `box/spout`, 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

Documentation can be found at [https://openspout.readthedocs.io/en/latest/](https://openspout.readthedocs.io/en/latest/).

## Requirements

* PHP version 7.3 or higher
* PHP extension `php_zip` enabled
* PHP extension `php_xmlreader` enabled

## Upgrade from `box/spout`

1. Replace `box/spout` with `openspout/openspout` in your `composer.json`
2. Replace `Box\Spout` with `OpenSpout` in your code

## 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 `main` 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: [![Build Status](https://travis-ci.org/box/spout.svg?branch=perf-tests)](https://travis-ci.org/box/spout)
