Excel Serialization

This module provides an Excel encoder for the Drupal 8 Serialization API. This
enables the XLS format to be used for data output (and potentially input,
eventually). For example:

• Drupal 8's REST module can return data in XLS format.
• Views can output XLS data via a 'REST Export' view, or a
  Data Export view.
• Module developers can leverage XLS as a format when using the Serialization
  API.

Installation

• Download and install PHPOffice/PHPExcel. The preferred installation method is to use Composer.
• Enable the xls_serialization module.

Creating an XLS view

1. Create a new view
2. Add a Data Export display (this assumes the use of the Views Data Export) module. Otherwise add a REST Export view.
3. Check only 'xls' for the accepted request formats under Format > Data export > Settings.
4. Add desired fields to the view.
5. Add a path, and optionally, a filename pattern.
