In plain words
What is it for?
Use it to read files, count and summarize records, filter rows, group data, create pivot tables and charts, validate cleaned data, and export results.
Why use it?
It reduces the manual work of inspecting large spreadsheets and repeating calculations or cleanup tasks.

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-analyzer 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 6d 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

Excel 分析

帮助用户分析和处理 Excel/CSV 文件。

使用场景

  • 用户说「帮我分析这个表格」「这个 Excel 里有多少条数据」
  • 用户需要对表格做筛选、汇总、透视
  • 用户想从 Excel 生成图表或报告

依赖安装

首次使用时自动安装:

pip install pandas openpyxl

执行方式

通过 Python 脚本使用 pandas 处理 Excel/CSV 文件。

读取文件

import pandas as pd

# 读取 Excel
df = pd.read_excel("/path/to/file.xlsx", sheet_name=0)

# 读取 CSV
df = pd.read_csv("/path/to/file.csv")

# 查看基本信息
print(f"行数: {len(df)}, 列数: {len(df.columns)}")
print(f"列名: {list(df.columns)}")
print(df.head())

数据汇总

# 基本统计
print(df.describe())

# 按列汇总
print(df.groupby("类别").agg({"金额": ["sum", "mean", "count"]}))

数据筛选

# 条件筛选
filtered = df[df["金额"] > 1000]

# 多条件
filtered = df[(df["部门"] == "销售") & (df["金额"] > 500)]

导出结果

# 导出到新 Excel
result.to_excel("/path/to/output.xlsx", index=False)

# 导出到 CSV
result.to_csv("/path/to/output.csv", index=False, encoding="utf-8-sig")

数据校验(必须执行)

分析前和分析后都要做数据校验,确保结果可信:

清洗后校验

# 1. 行数校验:打印清洗前后行数,确认只去了空行/噪音行
print(f"清洗前: {len(df_raw)} 行 → 清洗后: {len(df_clean)} 行 (去除 {len(df_raw)-len(df_clean)} 行)")

# 2. 分类列去重:检查分类列(如地区、产品)是否有近似重复值
for col in categorical_columns:
    unique_vals = df_clean[col].unique()
    print(f"列 '{col}' 唯一值: {unique_vals}")
    # 检查近似重复(如 "华东" vs "华东地区")
    # 如有近似重复,合并为统一值

# 3. 聚合一致性校验:各分组 sum 必须等于总 sum
total = df_clean["金额"].sum()
group_total = df_clean.groupby("地区")["金额"].sum().sum()
assert abs(total - group_total) < 0.01, f"聚合不一致: 总额 {total} ≠ 分组合计 {group_total}"

报告校验

  • 报告中引用的数字必须与清洗后数据一致
  • 如有排名/占比,各项占比之和应约等于 100%
  • 明确告知用户做了哪些清洗(统一了几种日期格式、去了多少空行等)

输出规范

  • 先展示数据概览(行数、列数、列名)
  • 明确告知清洗步骤:做了什么修复、去了多少行、统一了什么格式
  • 分析结果用表格格式展示
  • 大数据集只展示前 10 行 + 汇总统计
  • 导出文件时告知用户保存路径

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.
