Feature 1: Load HTML File

This feature shows how you can load your HTML document using GroupDocs.Conversion for .NET.

Step-by-Step Process

Initialize Converter

using System;
using GroupDocs.Conversion;
// Define the path to your document directory
string sourceHtmlPath = "YOUR_DOCUMENT_DIRECTORY\\sample.html";
// Create a new Converter instance for loading the HTML file
using (var converter = new Converter(sourceHtmlPath))
{
    Console.WriteLine("HTML loaded successfully!");
}

Explanation: The Converter class is initialized with your HTML document path, setting up the environment for conversion tasks.

Feature 2: Convert HTML to TXT

Converting an HTML file to a plain text format can be done efficiently using GroupDocs.Conversion.

Step-by-Step Process

Set Up Conversion Options

using System;
using System.IO;
using GroupDocs.Conversion;
using GroupDocs.Conversion.Options.Convert;
// Define the output directory path
string outputDirectory = "YOUR_OUTPUT_DIRECTORY";
string outputFile = Path.Combine(outputDirectory, "html-converted-to.txt");
// Create a new Converter instance for loading the HTML file
using (var converter = new Converter("YOUR_DOCUMENT_DIRECTORY\\sample.html"))
{
    // Set up conversion options for TXT format
    WordProcessingConvertOptions options = new WordProcessingConvertOptions { Format = GroupDocs.Conversion.FileTypes.WordProcessingFileType.Txt };
    
    // Perform the conversion from HTML to TXT and save the output file
    converter.Convert(outputFile, options);
    Console.WriteLine("Conversion completed successfully!");
}

Explanation: WordProcessingConvertOptions is configured for text format. The converter.Convert() method performs the actual conversion.
