Formatted_Export

This sub-skill covers one capability of the Excel workflow. For reading/counting/Parquet optimization, see the parent workflow SKILL.md.

Skill Steps

Step 1: Scan all sheets, locate the target column through fuzzy matching, and filter out records that meet the conditions (such as null values or invalid characters).

empty_target_rows = []
for sheet_name, sheet_df in all_sheets.items():
    target_col = None
    
    # 优先匹配目标列名（示例：包含特定关键字的列）
    for col in sheet_df.columns:
        if 'keyword1' in str(col).lower() or 'keyword2' in str(col).lower():
            target_col = col
            break

if target_col is None:
    # 尝试次级推断逻辑
    for col in sheet_df.columns:
        if 'keyword3' in str(col) and ('keyword4' in str(col)):
            target_col = col
            break
            
if target_col is None:
    continue

# 数据清洗：筛选空值和无效字符（如空格、'nan'）行
mask = sheet_df[target_col].isna() | (sheet_df[target_col].astype(str).str.strip() == '') | (sheet_df[target_col].astype(str).str.strip() == 'nan')
empty_rows = sheet_df[mask].copy()

if len(empty_rows) > 0:
    empty_rows.insert(0, '来源Sheet', sheet_name)
    empty_target_rows.append(empty_rows)

Merge results

result_df = pd.concat(empty_target_rows, ignore_index=True) if empty_target_rows else pd.DataFrame()


Step2 将筛选出的记录导出为 Excel 文件，整行标红显示以便于视觉识别，并生成下载链接。
```python
from openpyxl import load_workbook
from openpyxl.styles import PatternFill

output_path = "filtered_results_highlighted.xlsx"

if not result_df.empty:
    # 导出基础数据
    result_df.to_excel(output_path, index=False)

    # 加载工作簿进行格式化
    wb = load_workbook(output_path)
    ws = wb.active
    
    # 定义红色填充样式
    red_fill = PatternFill(start_color="FF0000", end_color="FF0000", fill_type="solid")

    # 遍历所有数据行并标红（跳过表头）
    for row in range(2, ws.max_row + 1):
        for col in range(1, ws.max_column + 1):
            ws.cell(row=row, column=col).fill = red_fill

    wb.save(output_path)
    print(f"结果文件已保存: {output_path}")
    print(f"下载链接: [点击下载标红结果文件]({output_path})")
else:
    print("未找到符合条件的记录，无需导出。")
