HTML, the backbone of web development, is widely used to build and present content on the web. While HTML is great for creating dynamic and interactive web pages, it is not well suited for creating professional-looking documents. When faced with such requirements, converting HTML to Word format is an ideal solution.
By implementing the Html to Word conversion, you can preserve the structure and content of the HTML while applying appropriate formatting and styles in Word to ensure the document look more professional. In this article, you will learn how to convert HTML to Word in React using Spire.Doc for JavaScript.
Install Spire.Doc for JavaScript
To get started with converting Word documents to PDF in a React application, you can either download Spire.Doc for JavaScript from our website or install it via npm with the following command:
npm i spire.doc
Make sure to copy all the dependencies to the public folder of your project. Additionally, include the required font files to ensure accurate and consistent text rendering.
For more details, refer to the documentation: How to Integrate Spire.Doc for JavaScript in a React Project
Convert an HTML File to Word with JavaScript in React
With Spire.Doc for JavaScript, you can simply load an HTML file and then save it as a Word Doc or Docx format through the Document.SaveToFile() function. The following are the main steps to convert an HTML file to Word in JavaScript.
- Load the font file to ensure correct text rendering.
- Create a new document using the wasmModule.Document.Create() function.
- Load the HTML file using the Document.LoadFromFile() function.
- Save the HTML file to a Word file using the Document.SaveToFile() function.

import React, { useState, useEffect } from 'react';
function App() {
// State to hold the loaded WASM module
const [wasmModule, setWasmModule] = useState(null);
// useEffect hook to load the WASM module when the component mounts
useEffect(() => {
const loadWasm = async () => {
try {
// Access the Module and spiredoc from the global window object
const { Module, spiredoc } = window;
// Set the wasmModule state when the runtime is initialized
Module.onRuntimeInitialized = () => {
setWasmModule(spiredoc);

script.src = `${process.env.PUBLIC_URL}/Spire.Doc.Base.js`;
script.onload = loadWasm;

// Save the HTML file to a Word file
doc.SaveToFile({fileName: outputFileName, fileFormat: wasmModule.FileFormat.Docx});
// Read the generated Word file from VFS
const modifiedFileArray = wasmModule.FS.readFile(outputFileName);
// Create a Blog object from the Word file

// Create a URL for the Blob
const url = URL.createObjectURL(modifiedFile);

const a = document.createElement("a");
a.href = url;
a.download = outputFileName;
document.body.appendChild(a);
a.click();
document.body.removeChild(a);
URL.revokeObjectURL(url);

doc.Dispose();

Run the code to launch the React app at localhost:3000. Once it's running, click on the "Convert" button to download the Word file generated from an HTML file:
Below is the input HTML file and the converted Word file:
Convert an HTML String to Word with JavaScript in React
You can also convert an HTML string to Word by calling the Paragraph.AppendHTML() function to add the HTML string to a paragraph in Word and then save the Word document. The following are the main steps to convert an HTML string to a Word file in JavaScript.
- Load the font file to ensure correct text rendering.
- Specify the HTML string
- Create a new document using the wasmModule.Document.Create() function.
- Add a new section using the Document.AddSection() function.
- Add a paragraph to the section using the Section.AddParagraph() function.
- Append the HTML string to the paragraph using the Paragraph.AppendHTML() function.
- Save the Word document using the Document.SaveToFile() function.
