Transform Excel Data with Pandas Pivot Table: A Step‑by‑Step Guide

1. Introduction

In a recent Python community discussion, a user asked how to reshape an Excel dataset using pandas. The goal was to convert the raw table into a pivot‑style format.

2. Problem Description

The original data (shown in the first image) contains multiple rows for each category, while the desired output (second image) aggregates these rows into a concise pivot table.

The target layout looks like the third image.

3. Solution Using pd.pivot_table()

One contributor suggested using pd.pivot_table() to achieve the transformation. Another participant provided a concrete code example, which is displayed in the following image.

A second solution was also shared, illustrated below.

Both approaches successfully generated the desired pivot table, resolving the user's issue.
