excel-large-file-processing-and-cleaning

excel-large-file-processing-and-cleaning is a skill for Claude Code, Codex from OpenSenseNova/SenseNova-Skills. It costs 41 tokens per session (578 once invoked), scanned A, original, MIT.

A spreadsheet-cleaning workflow for Excel files with multiple sheets. It can find relevant columns, count matching values, and keep only Chinese characters in selected text fields.

In plain words
What is it for?
Use it to clean name or address fields, find columns containing a keyword such as “type,” and count rows whose value matches a target such as “varchar.”
Why use it?
It reduces manual work when spreadsheets use inconsistent column names or contain text mixed with numbers and symbols. It produces a standardized Excel file for later use.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

excel-large-file-processing-and-cleaning scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually 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)。

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。

# 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}")
print(f"匹配列 '{target_col}' 中值为 '{target_val}' 的总数: {total_target_count}")
print(f"{'='*50}")
for detail in details:
    print(f"  {detail['sheet']}: {detail['target_count']} 个匹配项 (共 {detail['total_rows']} 行)")

Step3 将清洗和处理后的数据保存为 Excel,并输出文件大小与下载链接。

output_path = "/mnt/data/cleaned_data_output.xlsx"
df.to_excel(output_path, index=False)

file_size = os.path.getsize(output_path)
print(f"清洗后的数据已保存至: {output_path}")
print(f"文件大小: {file_size} 字节")
# 生成标准下载链接格式
print(f"下载链接: sandbox:{output_path}")

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
