Implementation Guide

In this section, we’ll walk through converting DOCX files to HTML format.

Convert DOCX to HTML

Overview

This feature allows you to convert a Word document into an HTML file while preserving its formatting and structure. This is particularly useful for web publishing or content management systems.

Step 1: Set Up Paths

Define your input and output paths:

using System;
using System.IO;

string inputFilePath = Path.Combine(@"YOUR_DOCUMENT_DIRECTORY", "sample.docx");
string outputFolder = @"YOUR_OUTPUT_DIRECTORY";
string outputFile = Path.Combine(outputFolder, "docx-converted-to.html");

if (!Directory.Exists(outputFolder))
{
    Directory.CreateDirectory(outputFolder);
}

Step 2: Load and Convert the Document

Use GroupDocs.Conversion to load your DOCX file and convert it:

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

// Load and convert DOCX to HTML
using (var converter = new Converter(inputFilePath))
{
    var options = new WebConvertOptions();
    converter.Convert(outputFile, options);
}

Explanation:

  • The Converter class loads the document.
  • WebConvertOptions configures conversion settings for HTML output.

Troubleshooting Tips

  • Ensure file paths are correct and accessible.
  • Verify if GroupDocs.Conversion is correctly installed and licensed.
