## How to Parse PPTX Files in C#

Basic document parsing with the [Aspose.Slides for .NET](/slides/net/) API requires just a few lines of code.

Load the PPTX file with `Presentation`.

Retrieve text frames with `SlideUtil.GetAllTextFrames`.

Iterate through text frames, paragraphs, and portions.

Read `Text`, `FontHeight`, and `LatinFont.FontName` properties as needed.

## System Requirements

A supported .NET runtime and an Aspose.Slides for .NET package reference are required. You can use Visual Studio or another compatible C# development environment.

- .NET Framework, .NET, Mono, or Xamarin-compatible environment
- A C# development environment such as Visual Studio

### Parse PPTX Files - C#

```cs
using var presentation = new Presentation("presentation.pptx");
var textFrames = SlideUtil.GetAllTextFrames(presentation, true);

foreach (var textFrame in textFrames)
{
    foreach (var paragraph in textFrame.Paragraphs)
    {
        foreach (var portion in paragraph.Portions)
        {
            Console.WriteLine(portion.Text);
            Console.WriteLine(portion.PortionFormat.FontHeight);

            var latinFont = portion.PortionFormat.LatinFont;
            if (latinFont is not null)
            {
                Console.WriteLine(latinFont.FontName);
            }

## About Aspose.Slides for .NET API

Aspose.Slides for .NET reads, writes, edits, and converts PowerPoint and OpenDocument presentations. It can create presentations, work with slides and their elements, and save to formats such as PDF, XPS, HTML, TIFF, and ODP without requiring Microsoft PowerPoint or OpenOffice.

PPTX files are presentations created with Microsoft PowerPoint. Unlike the binary PPT format, PPTX uses the Office Open XML format. A presentation contains slides with text, images, formatting, animations, and other media that are shown as a slideshow.

## Other Supported Parsing Formats

- [ODP](/slides/net/parser/odp/) — OpenDocument Presentation format
- [PPT](/slides/net/parser/ppt/) — PowerPoint 97-2003 Presentation
