Data can not be exported to Excel because the PHPExcel library is not
installed. This software component is required for Phabricator to create
Excel files.
You can install PHPExcel from GitHub:
> https://github.com/PHPOffice/PHPExcel
Briefly:
- Clone that repository somewhere on the sever
(like `/path/to/example/PHPExcel`).
- Update your PHP `%s` setting (in `php.ini`) to include the PHPExcel
`Classes` directory (like `/path/to/example/PHPExcel/Classes`).
