Pattener Inc. (Headquarters: Shinagawa-ku, Tokyo; Representative Director: Tsuguru Fukano) has released a free practical guide, "[Excel x Copilot Business Utilization Handbook] Best Practices for On-site Implementation, from Prompt Design to Security Measures," to maximize the business utilization of Microsoft Copilot in Excel.

This document goes beyond merely introducing tool functions, delving into best practices for successful Excel x Copilot implementation, from "prompt design methods" that can be immediately used on-site to "security measures" that information system departments should be aware of.

Background of Publication: Cloud Selection is a "Management" Issue, Not a "Technology" Issue

"Licenses were just granted," "Usage was left to the field."

Are you ending the introduction of generative AI in such a state?

Excel, the most familiar and frequently used tool in the business environment.

Mastering Copilot on this platform not only reduces routine work but also becomes an engine that dramatically accelerates the speed of data-driven decision-making.

This document explains how to directly connect Copilot's potential to "data analysis" and "operational efficiency" on-site.

It also covers mechanisms to prevent AI errors (hallucinations) and concepts of data governance to protect data, all explained in practical business language.

[Excel x Copilot Business Utilization Handbook] Best Practices for On-site Implementation, from Prompt Design to Security Measures

<Table of Contents>

Introduction

What is Excel Copilot? How will it change "data analysis"?

Overall picture of what can be done (summary, trends, outliers, visualization)

Reasons why "non-individualized analysis" is possible (ability to retain thought patterns)

Role sharing between traditional Excel analysis (pivot, functions) and Copilot

Points to note before introduction: Usage conditions, security, operation design

Organization of licenses / compatible environments / management requirements

Precautions for data handling (personal information, confidential information, auditing)

Guidelines for successful internal deployment (permissions, education, templates)

Basic workflow for "Copilot x Excel data analysis" effective in practice

Pre-analysis processing: First, "organize" — column definition, missing values, table format

Requesting analysis: How to create good questions (metrics, granularity, period, comparison)

"Productizing" output: Pivot / graph / summary saving techniques

Practical prompt design: Common failures and 10 stable instruction templates

Golden structure of request sentences (purpose → data → conditions → output → verification)

Common failure examples and how to fix them (ambiguity, lack of prerequisites, granularity mismatch)

10 practical templates (weekly reports / anomaly detection / factor decomposition)

Advanced edition: From statistics to machine learning with Python in Excel x Copilot

Availability and introduction guide for Python in Excel

Practical techniques for visualization, EDA, and feature design

Prediction models and validity verification (overfitting and accountability)

Case-by-case: Reproducible utilization scenarios by department (Sales / CS / Corporate Planning)

Sales: Pipeline health, winning/losing analysis

CS: Churn prediction, health score, action prioritization

Corporate Planning: Budget vs. actual variance, KPI tree, summary for decision-making

Summary

Tazuna, the easiest data catalog in the world to get started with

<Recommended for>
