How to Convert HTML to Word in Java

This section provides the details on how we can easily perform HTML to Word document conversion using Java code snippet.

  1. Authenticate API Credentials.
Configuration configuration = new Configuration("your-client-id", "your-client-secret");
ConvertApi apiInstance = new ConvertApi(configuration);
  1. Upload JSON File to Cloud Storage.
FileUploadApi fileUpload = new FileUploadApi(configuration);
File inputFile = new File("input.html");
fileUpload.uploadFile(new UploadFileRequest("input.html", inputFile));
  1. Set Conversion Parameters.
ConvertSettings settings = new ConvertSettings();
settings.setFilePath("input.html");
settings.setFormat("DOC");
settings.setOutputPath("converted.doc");
  1. Perform JSON to HTML conversion.
ConvertDocumentRequest request = new ConvertDocumentRequest(settings);
DocumentResult response = apiInstance.convertDocument(request);
System.out.println("Conversion successful! The resultant DOC file is saved at:" + response.getFilePath());
// More examples over https://github.com/groupdocs-conversion-cloud/groupdocs-conversion-cloud-dotnet
// Obtain your API credentials
string clientId = "XXXXXX-XXXXXXXXX-4088-9ca0-55c38f4b7f22";
string clientSecret1 = "XXXXXXXXXXXXXXXXXXXX";
// Create an instance of the Configuration class and initialize it with the Client ID & Client Secret
Configuration configuration = new Configuration(clientId, clientSecret);
// Define the API base URL to perform HTML to Word Document conversion operation
configuration.setApiBaseUrl("https://api.groupdocs.cloud");
// Initialize an instance of ConvertApi with the Configuration object
ConvertApi convertApi = new ConvertApi(configuration);
ConvertSettings settings = new ConvertSettings();
settings.setStorageName("internal");
settings.setFilePath("input.html");
settings.setFormat("DOC");
settings.setOutputPath("myResultant.doc");
// Use ConvertDocument method to convert HTML to Word document
ConvertDocumentRequest request = new ConvertDocumentRequest(settings);
List<StoredConvertedResult> response = convertApi.convertDocument(request);
// Check the response and print success message
if (response != null && response.equals("OK")) {
System.out.println("Conversion successful! Resultant Word document is saved at: " + response.getFilePath());
}

HTML to DOCX Conversion using cURL

If you prefer command-line tools, then you can easily perform HTML to DOCX conversion using cURL and GroupDocs.Conversion REST API.

Firstly, we need to generate a JWT access token and then, execute the following cURL command to transform a webpage to Word document and save the resultant DOCX in the cloud storage.

curl -v "https://api.groupdocs.cloud/v2.0/conversion" \
-X POST \
-H "accept: application/json" \
-H "authorization: Bearer {accessToken}" \
-H "Content-Type: application/json" \
-d "{  \"StorageName\": \"default\",  \"FilePath\": \"{sourceFile}\",  \"Format\": \"docx\",\"OutputPath\": \"{resultantFile}\"}"

Please replace sourceFile with the name of input HTML file, resultantFile with the name of resultant Word document and accessToken with personalized JWT access token.

  • In order to save the resultant Word document on local drive, please try using the following cURL command.
curl -v "https://api.groupdocs.cloud/v2.0/conversion" \
-X POST \
-H "accept: application/json" \
-H "authorization: Bearer {accessToken}" \
-H "Content-Type: application/json" \
-d "{  \"StorageName\": \"default\",  \"FilePath\": \"{sourceFile}\",  \"Format\": \"docx\"}" \
-o "{resultantFile}"
