Convert PPT to PPTX Format

If you’ve ever needed to convert PowerPoint files from the older PPT format to the newer PPTX format using .NET, you’re in the right place. In this step-by-step tutorial, we will walk you through the process using the Aspose.Slides for .NET API. With this powerful library, you can effortlessly handle such conversions with ease. Let’s get started!

Prerequisites

Before we dive into the code, make sure you have the following set up:

• Visual Studio: Ensure that you have Visual Studio installed and ready for .NET development.
• Aspose.Slides for .NET: Download and install the Aspose.Slides for .NET library from here.

Setting Up the Project

1. Create a New Project: Open Visual Studio and create a new C# project.

2. Add Reference to Aspose.Slides: Right-click on your project in the Solution Explorer, choose “Manage NuGet Packages,” and search for “Aspose.Slides.” Install the package.

3. Import Required Namespaces:

using Aspose.Slides;

Converting PPT to PPTX

Now that we have our project set up, let’s write the code to convert a PPT file to PPTX.

string dataDir = "Your Document Directory";
string outPath = "Your Output Directory";

string srcFileName = dataDir + "Conversion PPT to PPTX.ppt";
string destFileName = dataDir + "Conversion PPT to PPTX.pptx";

// Instantiate a Presentation object that represents a PPT file
Presentation pres = new Presentation(srcFileName);

// Saving the presentation in PPTX format
pres.Save(outPath, SaveFormat.Pptx);

In this code snippet:

• dataDir should be replaced with the directory path where your PPT file is located.
• outPath should be replaced with the directory where you want to save the converted PPTX file.
• srcFileName is the name of your input PPT file.
• destFileName is the desired name for the output PPTX file.
