21 Jun 20244 minutes to read

The Word document files are converted as EPUB v2.0 file format with few lines of code by using the Essential DocIO.

Assemblies and NuGet packages required

Refer to the following links for assemblies and NuGet packages required based on platforms to convert a Word document to EPUB file using the .NET Word Library (DocIO).

The following code illustrates how to convert the Word document to EPUB file.

//DocIO supports Word to EPUB in Windows Forms, UWP, WPF, ASP.NET Web, and MVC platforms alone
//Loads an existing document
WordDocument document = new WordDocument("Template.docx", FormatType.Docx);
//Exports the fonts used in the document
document.SaveOptions.EPubExportFont = true;
//Exports header and footer
document.SaveOptions.HtmlExportHeadersFooters = true;
//Saves the document as EPub file
document.Save("WordToEPub.epub", FormatType.EPub);
//Closes the document
document.Close();
'Loads an existing document
Dim document As New WordDocument("Template.docx", FormatType.Docx)
'Exports the fonts used in the document
document.SaveOptions.EPubExportFont = True
'Exports header and footer
document.SaveOptions.HtmlExportHeadersFooters = True
'Saves the document as EPub file
document.Save("WordToEPub.epub", FormatType.EPub)
'Closes the document
document.Close()
//Loads the template document 
Assembly assembly = typeof(App).GetTypeInfo().Assembly;
WordDocument document = new WordDocument(assembly.GetManifestResourceStream("Sample.Assets.Template.docx"), FormatType.Docx);
//Exports the fonts used in the document
document.SaveOptions.EPubExportFont = true;
//Exports header and footer
document.SaveOptions.HtmlExportHeadersFooters = true;
//Saves the document as EPub file
MemoryStream stream = new MemoryStream();
await document.SaveAsync(stream, FormatType.EPub);
//Saves the stream as Word file in local machine
Save(stream, "WordToEPub.epub");
//Closes the document
document.Close();

//Saves the Word document
async void Save(MemoryStream streams, string filename)
{
    streams.Position = 0;
    StorageFile stFile;
    if (!(Windows.Foundation.Metadata.ApiInformation.IsTypePresent("Windows.Phone.UI.Input.HardwareButtons")))
    {
        FileSavePicker savePicker = new FileSavePicker();
        savePicker.DefaultFileExtension = ".epub";
        savePicker.SuggestedFileName = filename;
        savePicker.FileTypeChoices.Add("Word Documents", new List<string>() { ".epub" });
        stFile = await savePicker.PickSaveFileAsync();
    }
    else
    {
        StorageFolder local = Windows.Storage.ApplicationData.Current.LocalFolder;
        stFile = await local.CreateFileAsync(filename, CreationCollisionOption.ReplaceExisting);
    }
    if (stFile != null)
    {
        using (IRandomAccessStream zipStream = await stFile.OpenAsync(FileAccessMode.ReadWrite))
        {
            //Write compressed data from memory to file
            using (Stream outstream = zipStream.AsStreamForWrite())
            {
                byte[] buffer = streams.ToArray();
                outstream.Write(buffer, 0, buffer.Length);
                outstream.Flush();
            }
        }
    }
    //Launch the saved Word file
    await Windows.System.Launcher.LaunchFileAsync(stFile);
}
