  • Markdown instructions

    A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.

  • Works with any LLM

    AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.

  • Self-contained

    Everything the model needs lives in the instructions — no extra files to sync.

  • Open source

    Published by OpenSenseNova on GitHub. Read the source before you install it.

Installation

Install the Pivot Table Cross Analysis AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

1

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
  4. Enable the skill in any chat where you want it available.
Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.
2

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills
git clone --depth 1 https://github.com/OpenSenseNova/SenseNova-Skills.git /tmp/SenseNova-Skills
mkdir -p .claude/skills
cp -r /tmp/SenseNova-Skills/skills/sn-da-excel-workflow/capability/excel-data-analysis/pivot-table-analysis .claude/skills/pivot-table-cross-analysis
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Pivot Table Cross Analysis in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Pivot Table Cross Analysis on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Pivot Table Cross Analysis is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

  • Loaded only when it is needed

    The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.

  • Switch models mid-chat

    Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Step1 对原始数据进行清洗与重构,处理 Excel 合并单元格导致的缺失值,并筛选核心分析列。

python
import pandas as pd

def preprocess_pivot_data(file_path, target_cols=['奖项', '项目名称', '成员', '单位']):
    """
    清理并重构数据列,处理合并单元格填充。
    """
    df = pd.read_excel(file_path)
    # 映射通用列名
    df.columns = target_cols
    
    # 关键技巧:处理合并单元格。ffill 前需确保数据按原始分类顺序排列
    # 假设第一列为分类标签(如奖项名称)
    df[target_cols[0]] = df[target_cols[0]].fillna(method='ffill')
    
    # 删除关键信息(如成员或单位)缺失的无效行
    df = df.dropna(subset=[target_cols[2], target_cols[3]])
    
    # 清洗字符串空格
    for col in df.select_dtypes(['object']).columns:
        df[col] = df[col].str.strip()
        
    return df

Step2 构建交叉分析表(Crosstab),计算不同维度下的频数分布及百分比占比。

python
def create_cross_analysis(df, index_col='单位', columns_col='奖项'):
    """
    构建交叉表并计算各分类维度的获奖/分布比例。
    """
    # 生成频数统计交叉表
    cross_table = pd.crosstab(df[index_col], df[columns_col])
    
    # 计算占比:各列(奖项)下各行(单位)的分布比例
    # div(axis=1) 表示按列求和后进行除法
    award_proportions = cross_table.div(cross_table.sum(axis=0), axis=1) * 100
    
    # 技巧:生成带有总计行和占比的汇总表
    summary = cross_table.copy()
    summary['总计'] = summary.sum(axis=1)
    summary.loc['合计'] = summary.sum()
    
    return cross_table, award_proportions, summary

Step3 配置中文字体并生成热力图可视化,直观展示各维度间的分布差异。

python
import matplotlib.pyplot as plt
import seaborn as sns

def generate_analysis_heatmap(proportions, output_path='analysis_heatmap.png'):
    """
    生成高分辨率热力图,支持中文字体显示。
    """
    # 关键技巧:中文字体配置,兼容不同系统环境
    plt.rcParams['font.sans-serif'] = ['SimHei', 'WenQuanYi Zen Hei', 'DejaVu Sans']
    plt.rcParams['axes.unicode_minus'] = False
    
    plt.figure(figsize=(14, 10))
    
    # 使用 Seaborn 绘制热力图,fmt='.2f' 保留两位小数
    sns.heatmap(
        proportions, 
        annot=True, 
        fmt='.2f', 
        cmap='YlGnBu', 
        linewidths=.5,
        cbar_kws={'label': '占比 (%)'}
    )
    
    plt.title('多维度分类占比分布热力图', fontsize=15, pad=20)
    plt.xlabel('分类维度 (Columns)', fontsize=12)
    plt.ylabel('分析对象 (Index)', fontsize=12)
    
    # 自动调整布局防止标签裁剪
    plt.tight_layout()
    plt.savefig(output_path, dpi=300, bbox_inches='tight')
    plt.close()

Step4 执行综合分析算法,提取各维度的 Top-N 表现对象并计算整体排名。

python
def extract_performance_insights(proportions, top_n=3):
    """
    分析各奖项/分类下的领先者,并计算整体加权表现。
    """
    insights = {}
    
    # 1. 提取每个分类维度的前 N 名
    top_performers = {}
    for category in proportions.columns:
        top_list = proportions[category].sort_values(ascending=False).head(top_n)
        top_performers[category] = top_list.to_dict()
    
    # 2. 计算整体表现排名(基于所有维度的平均占比)
    overall_performance = proportions.mean(axis=1).sort_values(ascending=False)
    
    insights['top_by_category'] = top_performers
    insights['overall_ranking'] = overall_performance.head(10).to_dict()
    
    return insights

Step5 导出分析结果为 Excel 多工作表格式,并提供下载链接。

python
from IPython.display import FileLink

def export_results(cross_table, proportions, insights_df, file_name='analysis_report.xlsx'):
    """
    将分析结果保存至 Excel 并在环境中生成下载链接。
    """
    with pd.ExcelWriter(file_name) as writer:
        cross_table.to_excel(writer, sheet_name='频数统计')
        proportions.to_excel(writer, sheet_name='占比分析')
        insights_df.to_excel(writer, sheet_name='综合排名')
    
    return FileLink(file_name)

Frequently asked questions

What does the Pivot Table Cross Analysis AI skill do?

利用交叉表与热力图对分类数据进行多维度占比分析,适用于奖项分布、绩效评估或市场占有率等结构化数据的清洗与可视化。

Why use Pivot Table Cross Analysis on TypingMind?

Because you install it once and use it with any model. Pivot Table Cross Analysis is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Pivot Table Cross Analysis in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/OpenSenseNova/SenseNova-Skills/tree/main/skills/sn-da-excel-workflow/capability/excel-data-analysis/pivot-table-analysis. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Pivot Table Cross Analysis?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Pivot Table Cross Analysis?

As many as you like. As long as a model supports skills, you can use Pivot Table Cross Analysis with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Pivot Table Cross Analysis AI skill free?

Yes. It is published on GitHub by OpenSenseNova under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
