Implementation Guide

Convert VSTX to PPTX

Overview: This feature demonstrates converting Visio (VSTX) files into PowerPoint presentations (PPTX) using GroupDocs.Conversion for .NET.

Step 1: Define Output Directory and File Path

Set up your output directory and specify where the converted file should be saved:

string outputFolder = "YOUR_OUTPUT_DIRECTORY";
string outputFile = Path.Combine(outputFolder, "vstx-converted-to.pptx");

Step 2: Load the Source VSTX File

Load your source VSTX file for conversion:

string sampleVstxPath = "YOUR_DOCUMENT_DIRECTORY/samples/sample.vstx"; // Path to input VSTX file

Step 3: Convert and Save the PPTX File

Use the Converter class and PresentationConvertOptions to perform the conversion:

using (Converter converter = new Converter(sampleVstxPath))
{
    PresentationConvertOptions options = new PresentationConvertOptions();
    // Convert and save the PPTX file.
    converter.Convert(outputFile, options);
}

Parameters & Method Purpose:

  • sampleVstxPath: Path to your source VSTX file.
  • options: Configures conversion settings for presentation format.

Troubleshooting Tips
