Converting HTML to Word documents is important for sharing, archiving, and keeping formatting consistent. It makes editing easier, works well with other tools, and meets industry standards. Plus, Word documents can be accessed offline and have a professional look, making them perfect for formal submissions. Overall, this conversion enhances accessibility and simplifies content management.
In this article, you will learn how to use Spire.Doc for Java to convert HTML files and strings into Word documents in Java.

Convert HTML File to Word in Java
To transform an HTML file into a Word document, you mainly use the Document class. This class offers methods that enable you to import HTML content from a file and export it into multiple formats including DOC and DOCX.
Steps for converting an HTML file to a Word document using Java:
- Instantiate a new Document object
- Import HTML content using the Document.loadFromFile() method.
- Save the modified document as a Word file using the Document.saveToFile().
- Java
import com.spire.doc.Document;
import com.spire.doc.FileFormat;
import com.spire.doc.Section;
import com.spire.doc.documents.XHTMLValidationType;
public class ConvertHtmlFileToWord {
public static void main(String[] args) {
// Create a Document object
Document document = new Document();
// Load an HTML file
document.loadFromFile("C:\\Users\\Administrator\\Desktop\\Html.html", FileFormat.Html, XHTMLValidationType.None);
// Get the first section
Section section = document.getSections().get(0);
// Set the page margins
section.getPageSetup().getMargins().setAll(2);
// Save the document to a Word file
document.saveToFile("output/ToWord.docx",FileFormat.Docx);
// Dispose resources
document.dispose();
}
}
Convert HTML String to Word in Java
In some scenarios, you may need to generate or modify HTML content at runtime—for example, when creating HTML strings from user input, database queries, or template engines. Instead of converting a static HTML file, Spire.Doc for Java allows you to render dynamic HTML content directly into a Word document using the Paragraph.appendHTML() method.
Steps for converting an HTML sting to a Word document using Java:
- Create a Document object.
- Add a section and a paragraph to the document.
- Read an HTML string from an HTML file or any other data sources.
- Render the HTML string into the document using the Paragraph.appendHTML() method.
- Saves the document as a Word file using the Document.saveToFile() method.
- Java
import com.spire.doc.Document;
import com.spire.doc.FileFormat;
import com.spire.doc.Section;
import com.spire.doc.interfaces.IParagraph;
import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Paths;
public class ConvertHtmlStringToWord {
public static void main(String[] args) throws IOException {
// Create a Document object
Document document = new Document();
// Add a section
Section section = document.addSection();
// Set the page margins
section.getPageSetup().getMargins().setAll(2);
// Add a paragraph
IParagraph paragraph = section.addParagraph();
// Read HTML string from a file
String htmlFilePath = "C:\\Users\\Administrator\\Desktop\\Html.html";
String htmlString = new String(Files.readAllBytes(Paths.get(htmlFilePath)), "UTF-8");
// Append the HTML string to the paragraph
paragraph.appendHTML(htmlString);
// Save the document to a Word file
document.saveToFile("output/ToWord.docx", FileFormat.Docx);
// Dispose resources
document.dispose();
}
}
