Follow these steps for converting a .potm file into HTML:

Step 1: Define Paths for Input and Output Files

Set directories for your input POTM files and output HTML files.

string documentDirectory = "YOUR_DOCUMENT_DIRECTORY"; // Update with your path
string outputDirectory = "YOUR_OUTPUT_DIRECTORY"; // Update with your path

class Constants
{
    public static string GetOutputDirectoryPath() => outputDirectory;
    
    public static string SAMPLE_POTM => Path.Combine(documentDirectory, "sample.potm");
}

Step 2: Perform the Conversion

Convert the POTM file to HTML using GroupDocs.Conversion.

using System.IO;
using GroupDocs.Conversion.Options.Convert;

string outputFile = Path.Combine(Constants.GetOutputDirectoryPath(), "potm-converted-to.html");

// Initialize converter with input file path
using (var converter = new Converter(Constants.SAMPLE_POTM))
{
    // Specify conversion options for HTML format
    var options = new WebConvertOptions();

    // Perform the conversion and save to the specified output file
    converter.Convert(outputFile, options);
}
