excel-smart-analysis-and-cleaning SKILL.md skillA
excel-smart-analysis-and-cleaning from opensensenova/sensenova-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

对多 Sheet Excel 进行智能清洗、跨表核对与可视化分析。。.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
Step1 对数据进行深度清洗，包括合并单元格填充（ffill）、正则化文本处理、RGB 颜色分量转换以及异常值识别。
```python
import re
def clean_data(df, target_col):
# 1. 处理合并单元格：向下填充
df[target_col] = df[target_col].ffill()
# 2. 正则清洗：去除数字前缀、特殊字符及首尾空格
def regex_clean(text):
if not isinstance(text, str): return text
text = re.sub(r'^\d+[\.\s\-]+', '', text) # 去除如 "1. " 的前缀
text = re.sub(r'[^\u4e00-\u9fa5a-zA-Z0-9]', '', text) # 仅保留中英数
return text.strip()
df[target_col] = df[target_col].apply(regex_clean)
# 3. 数值转换与 RGB 逻辑筛选（示例：筛选黑色/无色值）
# 假设列名为 'Red', 'Green', 'Blue'
rgb_cols = ['Red', 'Green', 'Blue']
for col in rgb_cols:
if col in df.columns:
df[col] = pd.to_numeric(df[col], errors='coerce').fillna(0)
if all(c in df.columns for c in rgb_cols):
black_mask = (df['Red'] == 0) & (df['Green'] == 0) & (df['Blue'] == 0)
df = df[black_mask]
return df
# 遍历所有 sheet 进行清洗
cleaned_dfs = {name: clean_data(df, 'group_col') for name, df in df_dict.items()}
```
Step2 执行跨表核对与多维度统计分析（如交叉分析、占比统计），并识别关键指标（如问题发现率）。
```python
# 跨表核对示例：核对 Sheet1 与 Sheet2 的数值合计
if 'Sheet1' in cleaned_dfs and 'Sheet2' in cleaned_dfs:

How to install
mdr add opensensenova/sensenova-skills/excel-smart-analysis-and-cleaning@sha256:514ea9975a943466The line at the top of this page pins the label git:20260426.f0ab496, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
