+Excel report engine helpers
+===========================
+
+This module provides a set of tools to facilitate the creation of excel reports with format xlsx.
+This module offers a similar functional coverage as the 8.0 version of the ``report_xls`` module.
+
+Usage
+=====
+
+In order to create an Excel report you can:
+
+- define a report of type 'xlsx'
+- pass ``{'xlsx_export': 1}`` via the context to the report create method
+
+The ``AbstractReportXlsx`` class contains a number of attributes and methods to
+facilitate the creation excel reports in Odoo.
+
+* Cell types
+
+  string, number, boolean, datetime.
+
+* Cell formats
+
+  The predefined cell formats result in a consistent
+  look and feel of the Odoo Excel reports.
+
+* Cell formulas
+
+  Cell formulas can be easily added with the help of the ``_rowcol_to_cell()`` method.
+
+* Excel templates
+
+  It is possible to define Excel templates which can be adapted
+  by 'inherited' modules.
+  Download the ``account_move_line_report_xls`` module
+  from http://apps.odoo.com as example.
+
+* Excel with multiple sheets
+
+  Download the ``account_asset_management_xls`` module
+  from http://apps.odoo.com as example.
+
+Installation
