+
+From a db query, this module allows to transform data in Polars
+dataframe and process them according to rules in order to:
+
+-  filter data and display
+-  obtain another dataframe with only the expected data to use in Odoo
+
+A such dataframe can help to prepare data in order to be used to
+create/update or import
+
+For that you need to transform/arrange data to the same way
+
+.. IMPORTANT::
+   This is an alpha version, the data model and design can change at any time without warning.
+   Only for development or testing purpose, do not use in production.
