+Stock Valuation XLSX
+====================
+
+This module generate nice XLSX stock valuation reports either:
+
+* from a physical inventory,
+* from present stock levels (i.e. from quants),
+* from past stock levels.
+
+It has several options:
+
+* filter per product category,
+* split by lots,
+* split by stock location,
+* display subtotals per category.
+
+You can access this XLSX stock valuation report either:
+
+* from the menu *Inventory > Reports > Stock Valuation XLSX* (it replaces the native menu *Inventory at Date*)
+* from the form view of *validated* inventories (menu *Inventory > Inventory Control > Inventory Adjustments*) via the button *XLSX Valuation Report*.
+
+This module has been written by Alexis de Lattre from Akretion <alexis.delattre@akretion.com>.
