### Streaming Write
`XLSX.stream.to_csv` is the streaming version of `XLSX.utils.sheet_to_csv`. It
takes the same arguments but returns a readable stream.
The streaming write functions are available in the `XLSX.stream` object. They
take the same arguments as the normal write functions but return a readable
stream. They are only exposed in node.
