Where did $worksheet came from?

It looks like it was accidentally omitted from the documentation. I will create a PR to address that. If you need a solution quickly, it probably comes from something like:

$worksheet = $spreadsheet->getActiveSheet();

There are also methods to retrieve a worksheet by title or by index.
