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) Documentation can be found at [`docs/`](docs). Upgrade from `box/spout:v3` to `openspout/openspout:v3` ------------------------------------------------------- [](#upgrade-from-boxspoutv3-to-openspoutopenspoutv3) 1. Replace `box/spout` with `openspout/openspout` in your `composer.json` 2. Replace `Box\Spout` with `OpenSpout` in your code Upgrade guide ------------- [](#upgrade-guide) Version 4 introduced new functionality but also some breaking changes. If you want to upgrade your OpenSpout codebase please consult the [Upgrade guide](UPGRADE.md).
