  • 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 Large File Parquet Analysis And Highlight 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-cell-coloring/category-coloring .claude/skills/large-file-parquet-analysis-and-highlight
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Large File Parquet Analysis And Highlight 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 Large File Parquet Analysis And Highlight 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 Large File Parquet Analysis And Highlight 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.

Skill Steps

Step1 读取文件并统计所有 sheet 的行数,汇总后打印总行数,用于判断数据规模是否需要启用大文件处理。

python
import pandas as pd

file_path = "input_data.xlsx"

# 读取所有sheet并统计总行数
xls = pd.ExcelFile(file_path)
sheet_names = xls.sheet_names
print(f"Sheet列表: {sheet_names}")

total_rows = 0
for sheet in sheet_names:
    # 仅读取一列以加快行数统计速度
    df_temp = pd.read_excel(file_path, sheet_name=sheet, usecols=[0], header=None)
    rows = len(df_temp)
    total_rows += rows
    print(f"Sheet '{sheet}': {rows} 行")

print(f"\n总行数 = {total_rows}")

Step2 当总行数 ≥ 1万时,读取已转换为 Parquet 格式的数据文件,通过行列匹配提取目标指标数据,并找出最大值及其对应分类。

python
import pandas as pd

# 假设已通过大文件处理技能将Excel转换为Parquet
parquet_path = "converted_data.parquet"
df = pd.read_parquet(parquet_path)

# 假设第2行(索引1)是分类表头(如:控股类型、区域等)
header_row = df.iloc[1].tolist()
print("分类表头:", header_row)

# 找到目标指标所在的行(占位示例:'目标指标名称')
target_metric = '目标指标名称'
target_rows = df[df[0] == target_metric]

if not target_rows.empty:
    # 提取数值
    values = target_rows.iloc[0, 1:].tolist()
    
    # 清洗数据并找出最大值及其对应的分类
    numeric_values = []
    for val in values:
        try:
            numeric_values.append(float(val))
        except:
            numeric_values.append(0)
    
    max_val = max(numeric_values)
    max_idx = numeric_values.index(max_val)
    max_type = header_row[1:][max_idx]
    
    print(f"\n指标最高的分类: {max_type} ({max_val})")
    
    # 准备写入Excel的数据结构
    result_data = list(zip(header_row[1:], numeric_values))

Step3 将提取的分析结果保存为新的 Excel 文件,并使用 openpyxl 对最大值所在行进行背景色高亮标注,最后验证输出。

python
from openpyxl import Workbook
from openpyxl.styles import PatternFill
from openpyxl import load_workbook

output_path = "analysis_result.xlsx"

wb = Workbook()
ws = wb.active
ws.title = "数据分析结果"

# 写入表头
headers = ["分类类型", "指标数值"]
ws.append(headers)

# 写入数据 (使用Step2提取的 result_data,此处为防空值做备用示例)
if 'result_data' not in locals():
    result_data = [("分类A", 100), ("分类B", 500), ("分类C", 200)]
    max_type = "分类B"

for row in result_data:
    ws.append(row)

# 找到最大值所在行并标绿
green_fill = PatternFill(start_color="00FF00", end_color="00FF00", fill_type="solid")

for row in ws.iter_rows(min_row=2, max_row=ws.max_row):
    if row[0].value == max_type:
        for cell in row:
            cell.fill = green_fill

# 保存文件
wb.save(output_path)
print(f"文件已保存到: {output_path}")

# 验证输出文件内容及格式
wb_check = load_workbook(output_path)
ws_check = wb_check.active
print("\n文件内容验证:")
for row in ws_check.iter_rows(values_only=True):
    print(row)

Frequently asked questions

What does the Large File Parquet Analysis And Highlight AI skill do?

当Excel文件总行数超过1万行时,通过转换为Parquet格式提升读取性能,提取目标指标并计算最大值,最后将结果输出为Excel并对特定行进行高亮标注。

Why use Large File Parquet Analysis And Highlight on TypingMind?

Because you install it once and use it with any model. Large File Parquet Analysis And Highlight 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 Large File Parquet Analysis And Highlight 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-cell-coloring/category-coloring. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Large File Parquet Analysis And Highlight?

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 Large File Parquet Analysis And Highlight?

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

Is the Large File Parquet Analysis And Highlight 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.
