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

读取多 sheet Excel 文件，动态识别目标列进行统计，并使用正则清洗文本字段提取中文字符，最终输出标准化 Excel 文件。.
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
# Skill Steps
> This sub-skill covers one capability of the Excel workflow. For reading/counting/Parquet optimization, see the parent workflow SKILL.md.
Step1 文本字段清洗，使用正则表达式提取纯中文字符（过滤数字、特殊符号等）。
```python
import re
def extract_chinese(text):
if pd.isna(text):
return text
# 仅保留 Unicode 中文字符范围
chinese_chars = re.findall(r'[一-龥]', str(text))
cleaned = ''.join(chinese_chars)
return cleaned if cleaned else ''
clean_col = '目标清洗列' # 占位示例，如'收货人'
if clean_col in df.columns:
df[clean_col] = df[clean_col].apply(extract_chinese)
```
Step2 动态模糊匹配列名，并统计该列中特定值的数量。
```python
# 动态查找包含特定关键字的列
keyword = 'type'
target_val = 'varchar'
target_col = next((col for col in df.columns if keyword in str(col).lower()), None)
total_target_count = 0
details = []
if target_col is not None:
# 忽略大小写和首尾空格进行匹配
mask = df[target_col].astype(str).str.lower().str.strip() == target_val
count = mask.sum()
total_target_count += count
if count > 0:
details.append({
'sheet': target_sheet,
'target_count': count,
'total_rows': len(df)
})
print(f"{'='*50}")

How to install
mdr add opensensenova/sensenova-skills/excel-large-file-processing-and-cleaning@sha256:33070ece70327fd3The 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.
