Convert HTML to DOCX in Java

2 min readJul 24, 2021

Microsoft Word DOCX documents are well-known for their compatibility, accessibility, and extensive style formatting. However, they also have a reputation for being notoriously hard to work with when it comes to document conversions. If you need to convert an HTML document to a Word file, you should put aside a good chunk of time to perform the manual process. Or, if you prefer to skip the headache and keep your productivity level high, you can use the following API in Java to instantly convert HTML to DOCX — no additional coding needed.

To get things started, we will install the Maven package by adding a reference to the repository in pom.xml:

<repositories>
    <repository>
        <id>jitpack.io</id>
        <url>https://jitpack.io</url>
    </repository>
</repositories>

Then, we will add a reference to the dependency:

<dependencies>
<dependency>
    <groupId>com.github.Cloudmersive</groupId>
    <artifactId>Cloudmersive.APIClient.Java</artifactId>
    <version>v4.25</version>
</dependency>
</dependencies>

After the installation, we can add the imports to the top of the controller and call the function:

// Import classes:
//import com.cloudmersive.client.invoker.ApiClient;
//import com.cloudmersive.client.invoker.ApiException;
//import com.cloudmersive.client.invoker.Configuration;
//import com.cloudmersive.client.invoker.auth.*;
//import com.cloudmersive.client.ConvertWebApi;ApiClient defaultClient = Configuration.getDefaultApiClient();// Configure API key authorization: Apikey
ApiKeyAuth Apikey = (ApiKeyAuth) defaultClient.getAuthentication("Apikey");
Apikey.setApiKey("YOUR API KEY");
// Uncomment the following line to set a prefix for the API key, e.g. "Token" (defaults to null)
//Apikey.setApiKeyPrefix("Token");ConvertWebApi apiInstance = new ConvertWebApi();
HtmlToOfficeRequest inputRequest = new HtmlToOfficeRequest(); // HtmlToOfficeRequest | HTML input to convert to DOCX
try {
    byte[] result = apiInstance.convertWebHtmlToDocx(inputRequest);
    System.out.println(result);
} catch (ApiException e) {
    System.err.println("Exception when calling ConvertWebApi#convertWebHtmlToDocx");
    e.printStackTrace();
}

Your new DOCX file will be ready to go at the end of the operation! Easy.
