+===============================
+Bank Statement Sheet Import UX
+===============================
+
+Most of the support around the statement sheet import comes from mappings that
+do not match the file the bank exports: a renamed header, a header row on the
+wrong line, the thousands separator the other way around. The error the user
+gets back (``'Debits' is not in list``) says nothing about which part of the
+mapping is wrong.
+
+ * Adds a **"Preview Mapping"** button on the statement sheet mapping. It shows a
+   sample sheet, with column letters and row numbers, built from the mapping as
+   it is configured right now: where the header row must be, which columns must
+   exist, and how dates and amounts must be written. Three sample transactions
+   are filled in so the layout is unambiguous.
+ * The sample can be downloaded as an **xlsx** file. Every cell is written as
+   text, the way the parser reads them, so the sample file can be imported with
+   that very mapping to check it end to end before fighting with the real
+   statement.
+ * The preview reads the mapping back to the user in plain words (date format,
+   separators, ignored rows and columns) and **warns about the configurations
+   that are going to fail**: a header row number of 0 (the header row is then
+   read as a transaction too and the spreadsheet import fails), or column names
+   on a mapping declared as having no header line.
+ * Rewrites the error of a **failed import**. Instead of the bare
+   ``'Date' is not in list``, it names the mapping and the column that is
+   missing (or the date format that does not match), tells the user to check the
+   Columns section and the preview, and offers a button that opens the mapping
+   right there.
+ * Matches the configured column names **ignoring case and padding**, so a bank
+   that exports ``DATE`` one month and ``Date`` the next one does not break the
+   import.
+ * Renames the ``Header lines skip count`` field to **Header row number** and
+   explains what the number means, which is where most of the wrong mappings
+   come from.
+ * Clears the amount columns when the **Amount type** changes, so a mapping
+   cannot keep columns that no longer apply to it.
+ * Stops rendering the statement PDF while a file is being imported. With
+   Enterprise installed, creating a bank statement renders its PDF
+   synchronously, and on a statement of a few hundred lines that render is what
+   makes the import time out. The attachment is also of no use to somebody who
+   is importing the file they already have.
+
+Technical notes
+===============
+
+ * The preview is built by ``account.statement.import.sheet.mapping._preview_layout()``,
+   which follows what the parser actually does: the header sits on
+   ``max(header_lines_skip_count, 1)`` and the transactions start right after
+   ``header_lines_skip_count``. Ignored rows carry a label so that they exist in
+   the exported file and the row numbers do not shift.
+ * With ``no_header`` the mapping holds column indexes, so each field lands on
+   the position it declares. With a header the file order is irrelevant to the
+   parser, so the preview lays the columns out in the order of the form and says
+   so.
+ * ``_get_column_indexes`` rewrites the header cells that match a configured
+   name to the configured spelling and delegates to the standard lookup, instead
+   of duplicating it. An unknown column still raises.
+ * ``_parse_decimal`` casts the raw ``int`` / ``float`` values the xls parser
+   hands over, which the standard method only handles for ``str``, ``float`` and
+   ``Decimal``.
+ * ``account.statement.import._parse_file`` catches the ``UserError`` the sheet
+   module raises and re-raises a ``RedirectWarning`` carrying the original text
+   plus the hint. The redirect action is built inline instead of pointing at a
+   preview record, because the failed transaction is rolled back and any record
+   created in that path would no longer exist when the user clicks the button.
+ * ``_create_bank_statements`` adds ``skip_pdf_attachment_generation`` to the
+   context. ``account_accountant`` reads that key in the ``create`` of
+   ``account.bank.statement`` to decide whether to call
+   ``action_generate_attachment()``; Odoo itself skips the render the same way
+   when importing statements (``l10n_be_codabox``, ``l10n_be_codaclean``).
+   Without Enterprise the flag is a no-op. It is injected on ``self`` rather
+   than on the values, because the base method builds the statement recordset
+   from ``self.env`` before extending its context with the per-statement
+   ``creation_context``, so the key survives without duplicating the method.
+
+Installation
+============
+
+Only install the module. It is auto installed as soon as
+``account_statement_import_sheet_file`` is installed, and it pulls
+``account_statement_import_sheet_file_xls`` and
+``account_statement_import_sheet_file_xlsx`` with it, so a base that can import
+csv statements can also import xls and xlsx ones.
+
+Configuration
+=============
+
+This module does not need any configuration.
+
+Usage
+=====
+
+Go to "Accounting > Configuration > Statement Sheet Mappings", open a mapping and
+click "Preview Mapping".
