+
+Installation
+============
+
+This module requires report_xlsx version 13.0.1.0.0 or higher.
+
+Usage
+=====
+
+In order to create an Excel report you can define a report of type 'xlsx' in a static or dynamic way:
+
+* Static syntax: cf. ``account_move_line_report_xls`` for an example.
+* Dynamic syntax: cf. ``report_xlsx_helper_demo`` for an example
+
+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.

+<p>In order to create an Excel report you can define a report of type ‘xlsx’ in a static or dynamic way:</p>
+<ul class="simple">
+<li>Static syntax: cf. <tt class="docutils literal">account_move_line_report_xls</tt> for an example.</li>
+<li>Dynamic syntax: cf. <tt class="docutils literal">report_xlsx_helper_demo</tt> for an example</li>
+</ul>
+<p>The <tt class="docutils literal">AbstractReportXlsx</tt> class contains a number of attributes and methods to
+facilitate the creation excel reports in Odoo.</p>
+<ul>
+<li><p class="first">Cell types</p>
+<p>string, number, boolean, datetime.</p>
+</li>
+<li><p class="first">Cell formats</p>
+<p>The predefined cell formats result in a consistent
+look and feel of the Odoo Excel reports.</p>
+</li>
+<li><p class="first">Cell formulas</p>
+<p>Cell formulas can be easily added with the help of the <tt class="docutils literal">_rowcol_to_cell()</tt> method.</p>
+</li>
+<li><p class="first">Excel templates</p>
+<p>It is possible to define Excel templates which can be adapted
+by ‘inherited’ modules.
