Implementation Guide

Convert MHTML to DOC Feature

Overview

The primary feature we’ll implement is converting an MHTML file into a Microsoft Word Document (DOC). This section details each step required for this transformation using GroupDocs.Conversion.

Step-by-Step Implementation

Load the Source MHTML File

To begin, load your source MHTML file. Ensure that the path to the file is correctly specified.

using System.IO;
using GroupDocs.Conversion;

// Define paths for input and output directories
string documentDirectory = "YOUR_DOCUMENT_DIRECTORY";
string outputDirectory = "YOUR_OUTPUT_DIRECTORY";

// Initialize the converter with the source MHTML file
using (var converter = new Converter(Path.Combine(documentDirectory, "sample.mhtml")))
{
    Console.WriteLine("MHTML file loaded.");
}
Define Conversion Options for DOC Format

Next, specify the conversion options. Here we set it to convert to Word Processing formats, specifically .doc.

using GroupDocs.Conversion.Options.Convert;

// Define conversion options for the DOC format
WordProcessingConvertOptions options = new WordProcessingConvertOptions 
{
    Format = GroupDocs.Conversion.FileTypes.WordProcessingFileType.Doc
};
Convert and Save the MHTML File as a DOC File

Finally, perform the conversion and save the output to your desired directory.

// Define the output file path for the converted document
string outputFile = Path.Combine(outputDirectory, "mhtml-converted-to.doc");

// Execute the conversion
converter.Convert(outputFile, options);

Console.WriteLine($"MHTML successfully converted to DOC: {outputFile}");

Troubleshooting Tips

  • Ensure that both input and output directories are correctly specified.
  • Verify that the GroupDocs.Conversion library is properly installed and referenced in your project.
  • If encountering file access errors, check for sufficient permissions on the paths involved.

Practical Applications

GroupDocs.Conversion isn’t just limited to MHTML-to-DOC conversions. Here are some real-world use cases:
