+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+**Auto_BOM** is a VBA code extraction and management toolkit for Excel-based Bill of Materials (BOM) processing. The project provides Python tools to extract VBA code from `.xlsm` (Excel) and `.accdb` (Access) files, manage it externally, and import it back.
+
+The VBA code implements a hierarchical BOM management system with:
+- **clsBOMManager**: Main class managing BOM data structure and category relationships
+- **clsCategory**: Represents material categories with hierarchical parent-child relationships
+- **clsMaterialItem**: Represents individual materials with code, name, quantity, and selection conditions
+
+## Directory Structure

+
+## Development Setup
+
+```bash
+# Create and activate virtual environment
+python -m venv .venv
+.venv\Scripts\activate  # Windows
+
+# Install dependencies
+pip install -r requirements.txt
+```
+
+**Dependencies:**
+- `pywin32>=306` - Windows COM interface for Excel/Access automation (Windows only)
+- `oletools>=0.60` - Alternative VBA extraction without Excel dependency (Excel only)
+
+## Common Commands
+
+### Extract VBA Code
+```bash
+# Interactive extraction - will prompt for file and method
+python extract_vba.py
+```
+
+**Excel (.xlsm)** - Two extraction methods available:
+1. **COM Interface** (recommended) - Requires Microsoft Excel, more reliable
+2. **olevba Library** - No Excel required, uses oletools
+
+**Access (.accdb)** - Only COM Interface supported (requires Microsoft Access)
+
+For COM method, ensure the application trusts VBA access:
+- Excel > Options > Trust Center > Trust Center Settings
+- Check "Trust access to the VBA project object model"
+
+### Import VBA Code
+```bash
+# Import from VBA/ directory back to Excel or Access
+python import_vba.py
+```
+
+Set `TARGET_FILE` in `.env` to the target `.xlsm` or `.accdb` file path.
+
+## VBA Code Architecture
+
+### BOM Data Model
+
+The VBA system implements a hierarchical category-based material management:
+
+1. **Two-source loading pattern**:
+   - `[平台配置清单]` sheet: Contains all material info (code, name, quantity, condition)
+   - `[领料配置]` sheet: Defines categories and which materials require picking
+
+2. **Category hierarchy**:
+   - Materials organized in parent-child category relationships
+   - `useParent=True`: Pick assembled components from parent category (default)
+   - `useParent=False`: Pick individual parts from child categories (fallback when stock insufficient)
+
+3. **Data structures**:
+   - `dictCategories`: Dictionary for fast category lookup by name
+   - `dictAllMaterials`: Dictionary for fast material lookup by code
+   - `rootCategories`: Collection of top-level categories for tree traversal
+
+### Module Types
+
+- **Modules**: Standard VBA modules (`.bas` files)
+- **ClassModules**: Class definitions (`.cls` files) - clsBOMManager, clsCategory, clsMaterialItem
+- **DocumentModules**: Sheet and workbook code-behind (`.cls` files)
+- **Forms**: UserForm definitions
+
+## Important Implementation Details
+
+### VBA Extraction (extract_vba.py)
+
+- Cleans `Attribute` statements from exported code for readability
+- Automatically categorizes modules by type (Standard/Class/Document/Form)
+- Module type detection based on naming conventions (mod_=Standard, cls=Class, sheet=Document)
+- Auto-detects file type by extension (.xlsm → Excel, .accdb → Access)
+
+### VBA Import (import_vba.py)
+
+- Uses Windows COM to interact with Excel or Access
+- **Critical fix for ClassModules**: Reconstructs `VERSION 1.0 CLASS` header before import
+- **Encoding handling**: Uses GB18030 for temp files to prevent Chinese character corruption
+- Path recognition logic handles relative/absolute paths in metadata
+- Two import strategies:
+  - **Modules/ClassModules**: Remove and re-import via file
+  - **DocumentModules/Forms**: Update code in-place via string injection
+
+### Module Naming Convention
+
+The code determines module type by naming prefix:
+- `mod_*` or `mod*` → Standard Modules
+- `cls*` or `class*` → Class Modules
+- `sheet*` or `thisworkbook` → Document Modules
+
+## VS Code Configuration
+
+The `.vscode/settings.json` associates `.cls` files with Visual Basic syntax highlighting for better editing experience.
+
+## Platform Requirements
+
+- **Windows required** for import functionality (COM interface)
+- **Microsoft Excel** required for Excel COM-based extraction/import
+- **Microsoft Access** required for Access COM-based extraction/import
+- Cross-platform extraction possible with oletools (Excel only, no Office needed)
+
+## Git Workflow
+
+The `.gitignore` excludes:
+- Virtual environment (`.venv/`)
+- Build artifacts (`build/`, `dist/`)
+- Project data (`Excel/`, `Access/`, `VBA/`)
+- Claude temporary files (`.claude/`, `tmpclaude-*`)
+
+Only commit code changes, not extracted VBA or Excel files.

+# Access (.accdb) VBA Code Export/Import Support Design
+
+## Summary
+
+Extend the existing `extract_vba.py` and `import_vba.py` to support Access `.accdb` files alongside Excel `.xlsm` files. The file type is auto-detected by extension via a unified `TARGET_FILE` env variable.
+
+## Key COM Differences
+
+| Dimension | Excel (.xlsm) | Access (.accdb) |
+|-----------|---------------|-----------------|
+| ProgID | `Excel.Application` | `Access.Application` |
+| Open | `Workbooks.Open(path)` | `OpenCurrentDatabase(path)` |
+| VBA Project | `workbook.VBProject` | `CurrentDb().VBE.VBProjects(1)` |
+| Close | `workbook.Close()` + `Quit()` | `CloseCurrentDatabase()` + `Quit()` |
+| Module types | Standard/Class/Document/Forms | Standard/Class only |
+
+## Changes
+
+### .env
+- Replace `TARGET_XLSM_FILE` with `TARGET_FILE` (supports `.xlsm` and `.accdb`)
+
+### extract_vba.py
+- Replace `TARGET_XLSM_FILE` with `TARGET_FILE`
+- Add `extract_vba_modules_access_com()` method to `VBAExtractor`
+- Update `main()` to detect file type by extension and auto-select COM method
+- Skip olevba option for `.accdb` files (unsupported)
+
+### import_vba.py
+- Replace `TARGET_XLSM_FILE` with `TARGET_FILE`
+- Add `import_vba_access()` method to `VBAImporter`
+- Update `main()` to detect file type by extension and route accordingly
+
+## Out of Scope
+- Access Forms/Reports VBA code (user doesn't need it)
+- olevba for Access files (unsupported)
+- Directory structure changes (Modules/ClassModules sufficient)

+# Access (.accdb) VBA Support Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Add Access `.accdb` VBA extraction and import support alongside existing Excel `.xlsm` support, using a unified `TARGET_FILE` config variable.
+
+**Architecture:** Extend the existing `VBAExtractor` and `VBAImporter` classes with Access COM methods. File type auto-detected by extension (`.xlsm` → Excel, `.accdb` → Access). Reuse existing module processing pipeline (`parse_attributes`, `_process_module`, `_scan_modules`, `_reconstruct_file_content`).
+
+**Tech Stack:** pywin32 (COM automation), Access.Application ProgID
+
+---
+
+### Task 1: Update `.env` config variable
+
+**Files:**
+- Modify: `.env:8`
+- Modify: `.env:5-8` (comments)
+
+**Step 1: Rename variable and update comments**
+
+Change `.env` from:
+```
+TARGET_XLSM_FILE=C:\Users\Administrator\Desktop\生产周期核对\常规产品生产周期.xlsm
+```
+To:
+```
+TARGET_FILE=C:\Users\Administrator\Desktop\生产周期核对\常规产品生产周期.xlsm
+```
+
+Update the comment block (lines 5-7) to reflect the new unified variable that supports both `.xlsm` and `.accdb`.
+
+**Step 2: Commit**
+
+```bash
+git add .env
+git commit -m "refactor: rename TARGET_XLSM_FILE to TARGET_FILE for unified file type support"
+```
+
+---
+
+### Task 2: Update `extract_vba.py` — config, constructor, and file type helper
+
+**Files:**
+- Modify: `extract_vba.py:23` (config var)
+- Modify: `extract_vba.py:38-69` (constructor — rename `self.xlsm_path` to `self.source_path`)
+- Modify: `extract_vba.py:129,171` (references to `self.xlsm_path`)
+- Add: file type helper function after constants block
+
+**Step 1: Replace `TARGET_XLSM_FILE` with `TARGET_FILE`**
+
+Line 23: `TARGET_XLSM_FILE` → `TARGET_FILE`
+Lines 21-26 — update comment block accordingly.
+
+**Step 2: Add file type helper function**
+
+Add after the constants block (after line 32), before the class:
+
+```python
+# 支持的文件类型
+ACCESS_EXTENSIONS = {'.accdb', '.mdb'}
+EXCEL_EXTENSIONS = {'.xlsm', '.xls', '.xlsb'}
+
+
+def get_file_type(file_path: Path) -> str:
+    """
+    根据文件扩展名判断文件类型
+
+    Returns:
+        'access' 或 'excel'
+    """
+    ext = file_path.suffix.lower()
+    if ext in ACCESS_EXTENSIONS:
+        return 'access'
+    return 'excel'
+```
+
+**Step 3: Rename `self.xlsm_path` to `self.source_path` throughout the class**
+
+In `__init__`: `self.xlsm_path` → `self.source_path` (line 46, 58)
+In `extract_vba_modules_olevba`: `self.xlsm_path.name` → `self.source_path.name` and `str(self.xlsm_path)` → `str(self.source_path)` (lines 129, 132)
+In `extract_vba_modules_com`: `self.xlsm_path.name` → `self.source_path.name` and `str(self.xlsm_path.absolute())` → `str(self.source_path.absolute())` (lines 171, 178)
+Also update the docstring in `__init__` (line 43-44): `xlsm_path: xlsm文件路径` → `source_path: 源文件路径（支持.xlsm和.accdb）`
+Rename the parameter from `xlsm_path` to `source_path`.
+
+**Step 4: Commit**
+
+```bash
+git add extract_vba.py
+git commit -m "refactor: rename xlsm_path to source_path and add file type detection helper"
+```
+
+---
+
+### Task 3: Add `extract_vba_modules_access_com()` to `VBAExtractor`
+
+**Files:**
+- Modify: `extract_vba.py` — add method after `extract_vba_modules_com()` (after line 245)
+
+**Step 1: Add the Access COM extraction method**
+
+Insert after line 245 (end of `extract_vba_modules_com`):
+
+```python
+    def extract_vba_modules_access_com(self):
+        """

+
+**Files:**
+- Modify: `extract_vba.py:342-438` (entire `main()` function)

+- File validation accepts both `.xlsm` and `.accdb`
+- Interactive mode scans for both extensions
+- Auto-selects COM method for `.accdb` (skips olevba prompt)
+- Instantiates `VBAExtractor` with `source_path` parameter

+
+---
+
+### Task 6: Update `import_vba.py` `main()` for unified file dispatch
+
+**Files:**
+- Modify: `import_vba.py:292-368` (entire `main()` function)
+
+**Step 1: Rewrite `main()` to support both file types**
+
+Replace the entire `main()` function. Key changes:
+- `TARGET_XLSM_FILE` → `TARGET_FILE`
+- File validation accepts both `.xlsm` and `.accdb`
+- Auto-selects import method based on file type
+- Display appropriate warning message
+
+```python

+        print("错误: 未配置 TARGET_FILE")

+    if not target_path.is_absolute():
+        target_path = script_dir / target_path
+
+    if not target_path.exists():
+        print(f"错误: 配置的文件不存在: {target_path}")
+        return
+

+        print(f"错误: VBA 代码目录不存在: {vba_path}")
+        print()
+        print("提示:")

+        return
+
+    type_label = "Access" if file_type == "access" else "Excel"
+    print(f"目标文件: {target_path.name} ({type_label})")
+    print(f"VBA 代码目录: {vba_path}")
+    print()
+
+    # 确认操作
+    print("=" * 60)
+    print(f"警告: 此操作将覆盖目标{type_label}文件中的 VBA 代码。")
+    choice = input("\n确认继续? (y/n): ").lower().strip()
+
+    if choice != 'y':
+        print("操作已取消")
+        return
+
+    importer = VBAImporter(str(vba_path), str(target_path))
+
+    # 显示模块数量
+    modules = importer._scan_modules()
+    print(f"找到 {len(modules)} 个模块文件")
+    print()
+    print("=" * 60)

+    if success:
+        print("导入成功完成！")
+    else:
+        print("导入失败")
+    print("=" * 60)
+```
+
+Note: `main()` in `import_vba.py` also needs the `get_file_type` helper. Add the same helper function and constants to `import_vba.py` (or extract to a shared module — but per the design, we keep it simple with duplication since the helper is tiny).
+
+**Step 2: Add the file type helper to `import_vba.py`**
+
+Add after the constants block (after line 40), same as in `extract_vba.py`:
+
+```python
+# 支持的文件类型
+ACCESS_EXTENSIONS = {'.accdb', '.mdb'}
+EXCEL_EXTENSIONS = {'.xlsm', '.xls', '.xlsb'}
+
+
+def get_file_type(file_path: Path) -> str:
+    """
+    根据文件扩展名判断文件类型
+
+    Returns:
+        'access' 或 'excel'
+    """
+    ext = file_path.suffix.lower()
+    if ext in ACCESS_EXTENSIONS:
+        return 'access'
+    return 'excel'
+```
+
+**Step 3: Commit**
+
+```bash
+git add import_vba.py
+git commit -m "feat: update import_vba.py main() to support both Excel and Access files"
+```
+
+---
+
+### Task 7: Update `.gitignore` and `CLAUDE.md` docs
+
+**Files:**
+- Modify: `.gitignore:17` (add `Access/` directory)
+- Modify: `CLAUDE.md` (update docs to reflect Access support)
+
+**Step 1: Add Access directory to `.gitignore`**
+
+After line 17 (`Excel/`), add:
+```
+Access/
+```
+
+**Step 2: Update `CLAUDE.md`**
+
+Update the project overview to mention Access support:
+- Project description: mention `.accdb` alongside `.xlsm`
+- Directory structure: add `Access/` source directory
+- Common commands: update descriptions to mention Access files
+- Platform requirements: add "Microsoft Access" as optional
+
+**Step 3: Commit**
+
+```bash
+git add .gitignore CLAUDE.md
+git commit -m "docs: update documentation for Access file support"
