+
+  The predefined cell formats result in a consistent

+
+* 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
