Excel数据向导

|---|
| 数据报表生成 | 数据源(JSON/CSV/DB)+ 模板 | 格式化的 Excel 报表 + 图表 |
| Excel 模板填充 | 模板文件 + 数据 | 填充后的 Excel 文件 |
| 批量数据处理 | 多个 Excel 文件 + 处理规则 | 合并/拆分/汇总后的 Excel |
| 格式美化 | 原始 Excel 文件 | 美化后的 Excel(字体/颜色/边框) |
| 图表可视化 | 数据 + 图表类型 | 含图表的 Excel 文件 |
| 财务报表自动化 | 财务数据 + 报表模板 | 月度/季度/年度财务报表 |
不适用于:
- 超大规模数据(>100万行,建议用 pandas + 数据库)
- 复杂的数据分析与建模(使用 pandas/numpy/scikit-learn)
- 实时协作编辑(使用 Google Sheets/飞书表格)
- 复杂的 VBA 宏开发(本 Skill 用 Python 替代)
- Excel 文件密码破解(不涉及安全破解)
- PDF/Word 等非 Excel 文件处理(使用专用工具)
- 在线表格 API 集成(使用 Google Sheets API/飞书开放平台)

操作流程

Step 1: 文件分析

1. 读取文件:加载 Excel 文件,获取工作簿与 Sheet 信息
2. 结构识别:Sheet 列表、每 Sheet 的行列数、表头识别、数据类型推断
3. 内容预览:前 10 行数据预览,确认数据结构
4. 问题诊断:格式问题、数据错误、缺失值、重复值

Step 2: 数据读取

1. 基础读取:openpyxl.load_workbook() 加载文件
2. 批量读取:按行/列批量读取,提高性能
3. 数据类型处理:数字/文本/日期/布尔值的正确解析
4. 公式值获取:data_only=True 获取计算结果,False 获取公式

Step 3: 数据写入与修改

1. 单元格写入:cell.value = value
2. 批量写入:按行/列批量写入,使用 append() 方法
3. Sheet 操作:创建/复制/移动/删除/重命名 Sheet
4. 数据校验:数据有效性(下拉列表/数字范围/日期范围)

Step 4: 格式化

1. 字体格式:字体名/大小/颜色/加粗/斜体/下划线
2. 填充格式:背景色/渐变/图案
3. 边框格式:边框样式/颜色/位置
4. 对齐格式:水平/垂直对齐/换行/缩进
5. 数字格式:数字/货币/百分比/日期/自定义格式
6. 条件格式:数据条/色阶/图标集/公式条件

Step 5: 公式与图表

1. 公式写入:cell.value = "=SUM(A1:A10)"
2. 图表创建:
   - 选择数据范围
   - 创建图表对象(BarChart/LineChart/PieChart)
   - 配置标题/图例/坐标轴
   - 添加到 Sheet
3. 图表样式:颜色/样式/数据标签

Step 6: 高级功能

1. 数据透视表:创建 PivotTable,配置行/列/值/筛选
2. 批注:添加单元格批注
3. 保护:Sheet 保护/工作簿保护/密码
4. 合并单元格:合并/拆分单元格

Step 7: 保存与导出

1. 保存文件:workbook.save('output.xlsx')
2. 格式兼容:确保 Microsoft Excel 与 WPS 表格兼容
3. 文件大小优化:移除未使用的样式与格式

Excel 与 WPS 表格兼容性
