C#: Convert PowerPoint to Markdown
PowerPoint presentations are widely used tools for visual communication, enabling users to effectively present information in an organized and visually engaging manner. They are ideal for business meetings, educational purposes, and project presentations. However, in some cases, converting PowerPoint presentations into a lightweight, text-based format such as Markdown is more practical.
Markdown is a popular markup language that is widely supported across documentation tools, version control systems, and static site generators. It offers a simple way to format text that is easier to read and write. By converting PowerPoint presentations to Markdown, users can integrate their content into text-based workflows more efficiently. This is especially helpful when collaborating on documents, tracking changes, or publishing content online.
In this article, we will walk you through the steps of converting PowerPoint presentations to Markdown format using C# and the Spire.Presentation for .NET library.
Install Spire.Presentation for .NET
To begin with, you need to add the DLL files included in the Spire.Presentation for.NET package as references in your .NET project. The DLL files can be either downloaded from this link or installed via NuGet.

ppt.LoadFromFile(@"E:\Program Files\Sample.pptx");
//Specify the file path for the output Markdown file
string result = @"E:\Program Files\PowerPointToMarkdown.md";
//Save the PowerPoint presentation to Markdown format
ppt.SaveToFile(result, FileFormat.Markdown);
}
}
}
Convert a Specific PowerPoint Slide to Markdown
In some cases, you may need to convert a specific slide instead of the whole presentation to Markdown. Spire.Presentation offers the ISlide.SaveToFile(string, FileFormat) method to convert a PowerPoint slide to Markdown. The following are the detailed steps:

{
internal class Program
{
static void Main(string[] args)
{
//Initialize an instance of the Presentation class
Presentation ppt = new Presentation();
//Load a PowerPoint presentation
ppt.LoadFromFile(@"E:\Program Files\Sample.pptx");
//Get the second slide
ISlide slide = ppt.Slides[1];
//Specify the file path for the output Markdown file
string result = @"E:\Program Files\SlideToMarkdown.md";
//Save the slide to a Markdown file

How to Convert PowerPoint Document to SVG Images in C#, VB.NET
SVG, short for scalable vector graphics, is a XML-based file format used to depict two-dimensional vector graphics. As SVG images are defined in XML text lines, they can be easily searched, indexed, scripted, and supported by most of the up to date web browsers. Therefore, office documents are often converted to SGV images for high fidelity viewing. Following sections will introduce how to convert PowerPoint documents to SVG images using Spire.Presentation in C# and VB.NET.
Code Snippet:
Step 1: Initialize an instance of Presentation class and load a sample PowerPoint document to it.
Presentation ppt = new Presentation(); ppt.LoadFromFile(@"C:\Users\Administrator\Desktop\sample.pptx");
Step 2: Convert PowerPoint document to byte array and store in a Queue object.
Queue<Byte[]> svgBytes = ppt.SaveToSVG();
Step 3: Initialize an instance of the FileStream class with the specified file path and creation mode. Dequeue the data in the Queue object and write to the stream.
int len = svgBytes.Count;
for (int i = 0; i < len; i++)
{
FileStream fs = new FileStream(string.Format("result" + "{0}.svg", i), FileMode.Create);
byte[] bytes = svgBytes.Dequeue();
fs.Write(bytes, 0, bytes.Length);
}
Output:

How to convert PowerPoint document to EMF image in C#
Spire.Presentation has powerful functions to export PowerPoint documents into different image file formats. In the previous articles, we have already shown you how to convert PowerPoint documents into TIFF, PNG and JPG. This article will demonstrate how to convert PowerPoint documents into EMF image. With Spire.Presentation for .NET, we can save presentation slides as an EMF image with the same size with the original slide's size and we can also set a specific size for the resulted EMF image.

Presentation presentation = new Presentation();
Step 2: Load the PPTX file from disk.
presentation.LoadFromFile("Sample.pptx", FileFormat.Pptx2010);
Step 3: Save the presentation slide to EMF image by the method of SaveAsEMF().
presentation.Slides[2].SaveAsEMF("Result.emf");
Effective screenshot:
Convert Presentation slides to EMF with a specific size of 1075*710:
Step 1: Create a presentation document.
