How to Replace Text in PowerPoint Slides Using Python

Have you ever found yourself overwhelmed with the task of updating PowerPoint presentations, especially when the content is stored externally, like in an Excel file? If so, you're in the right place! In this guide, we explore how you can easily replace slide content using Python, specifically leveraging the power of the openpyxl and python-pptx libraries. This guide will give you a step-by-step understanding of how to modify both titles and paragraphs in your presentation using data from an Excel file.

The Problem

Slide 1:

Title (ABC)

Body (The first name is ABC)

Slide 2:

Body (The last name is ABC)

Your goal is to replace the content in the presentation slides with the corresponding values from the Excel file so that it looks like this:

Slide 1:

Man

The first name is Tim

Slide 2:

The last name is Knight

Let’s dive into how to achieve this using Python.

The Solution

We will employ two libraries: openpyxl for handling Excel files and python-pptx for working with PowerPoint presentations. Below are the essential steps you'll need to follow in your code.

Step 1: Import the Required Libraries

First, make sure you have both libraries installed. You can install them using pip if you haven’t done so already:
