How to Convert DOCX to HTML in Node.JS

As the Word Document format is highly recognizable and user-friendly, it is often the go-to format for creating text documents. However, when using a Word document to draft code such as HTML, the extra formatting and styles associated with the file format can interfere with its use. With the following API, you can instantly convert any DOCX file to HTML, improving compatibility and product quality.

Install the SDK by running this command:

npm install cloudmersive-convert-api-client --save

Or, you can add this snippet to your package.json:

"dependencies": {
"cloudmersive-convert-api-client": "^2.4.8"

Then, you can call the function:

var CloudmersiveConvertApiClient = require('cloudmersive-convert-api-client');
var defaultClient = CloudmersiveConvertApiClient.ApiClient.instance;
// Configure API key authorization: Apikey
var Apikey = defaultClient.authentications['Apikey'];
Apikey.apiKey = 'YOUR API KEY';
var apiInstance = new CloudmersiveConvertApiClient.ConvertDocumentApi();var inputFile = Buffer.from(fs.readFileSync("C:\\temp\\inputfile").buffer); // File | Input file to perform the operation on.var callback = function(error, data, response) {
if (error) {
} else {
console.log('API called successfully. Returned data: ' + data);
apiInstance.convertDocumentDocxToHtml(inputFile, callback);

You can retrieve the API Key for this function at no cost and with no commitment on the Cloudmersive website. This will give you access to 800 monthly calls across our entire API library.
