How to get HTML content C# from an editable document

Below is the step‑by‑step guide that shows how to extract HTML, which is essentially the same as how to extract html from a document. The same flow also demonstrates convert docx to html and convert word to html.

Step 1: Create a FileStream for Your Document

Open the source file with a FileStream. This stream feeds the editor with the document’s bytes.

using (FileStream fs = File.OpenRead("Your Sample Document"))
{
    // Next steps will be placed here
}

Step 2: Initialize the Editor

Inside the using block, instantiate the Editor class. The delegate provides the stream, and the load options tell the editor which format you’re handling (WordProcessing in this case).

using (Editor editor = new Editor(delegate { return fs; }, delegate { return new WordProcessingLoadOptions(); }))
{
    // Next steps will be placed here
}

Step 3: Edit the Document

Create an EditableDocument using the Edit method. This object represents the document in an editable state and gives you access to its HTML content.

using (EditableDocument document = editor.Edit(new WordProcessingEditOptions()))
{
    // Next steps will be placed here
}

Step 4: Extract HTML Content

Finally, call GetContent() on the EditableDocument. The method returns the entire document as an HTML string. For demonstration we print the first 200 characters.

string htmlContent = document.GetContent();
Console.WriteLine("HTML content of the input document (first 200 chars): {0}", htmlContent.Substring(0, 200));
