8 OpenSpout is a community driven fork of `box/spout`, a PHP library to read and write spreadsheet files
9 (CSV, XLSX and ODS), in a fast and scalable way. Unlike other file readers or writers, it is capable of processing
10 very large files, while keeping the memory usage really low (less than 3MB).
14 Documentation can be found at [`docs/`](docs).
16 ## Upgrade from `box/spout:v3` to `openspout/openspout:v3`
