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 can be found at docs/.

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

Version 4 introduced new functionality but also some breaking changes. If you want to upgrade your OpenSpout codebase please consult the Upgrade guide.
