{
    static void Main()
    {
        string documentDirectory = @"C:\\\\Your\\\\Document\\\\Path";
        using (var converter = new Converter(documentDirectory + "/sample.dotx"))
        {
            // Your conversion logic will go here.
        }
    }
}

Implementation Guide

Let’s break down the implementation into distinct features.

Loading a Source File

Overview: Start by loading your DOTX file using GroupDocs.Conversion, preparing it for transformation to PPTX format.

Step-by-Step Process:

Define Document Directory Set the path where your document resides. Replace @YOUR_DOCUMENT_DIRECTORY with the actual path.

string documentDirectory = @"C:\\\\Your\\\\Document\\\\Path";

Load the DOTX File Initialize a Converter object to load the DOTX file.

using (var converter = new Converter(documentDirectory + "/sample.dotx"))
{
    // The document is now loaded and ready for conversion.
}

Explanation: This snippet initializes the Converter class, which facilitates loading your source document into memory for subsequent processing steps.

Configuring Conversion Options

Overview: Configure how your DOTX file will be converted to PPTX by setting up the necessary options.

Step-by-Step Process:

Create PresentationConvertOptions Instance

var options = new PresentationConvertOptions();

Explanation: Here, we create an instance of PresentationConvertOptions, which allows you to configure conversion settings such as slide size and format. By default, it uses standard PPTX configurations.

Saving a Converted File

Overview: Once configured, save your converted PPTX file using the defined options.

Step-by-Step Process:

Define Output Paths Set up your output directory and file path.

string outputDirectory = @"C:\\\\Your\\\\Output\\\\Path";
string outputFile = System.IO.Path.Combine(outputDirectory, "dotx-converted-to.pptx");

Convert and Save the File

using (var converter = new Converter(documentDirectory + "/sample.dotx"))
{
    var options = new PresentationConvertOptions();
    // Save the converted file to the specified path
    converter.Convert(outputFile, options);
}

Explanation: The Convert method applies your conversion settings and saves the output in the designated location.
