Transform MHTML to DOTX via Java

On Premise Java API to Render MHTML to DOTX without using any third party application

Converting MHTML to DOTX is a simple two-step process that can be accomplished with the help of Aspose.Total for Java. Aspose.Total for Java is a comprehensive suite of APIs that provides powerful document processing capabilities.

The first step is to render the MHTML file to DOC using Aspose.PDF for Java. Aspose.PDF for Java is a powerful PDF manipulation API that enables developers to create, edit, and convert PDF documents. It also provides the ability to render MHTML files to DOC.

The second step is to convert the DOC file to DOTX using Aspose.Words for Java. Aspose.Words for Java is a powerful document processing API that enables developers to create, edit, and convert documents. It provides the ability to convert DOC files to DOTX.

By using Aspose.Total for Java, developers can easily convert MHTML to DOTX in just two simple steps. Aspose.PDF for Java is used to render the MHTML file to DOC, and Aspose.Words for Java is used to convert the DOC file to DOTX. This makes it easy for developers to convert MHTML to DOTX quickly and efficiently.

Java API to Convert MHTML to DOTX

Open MHTML file using Document class
Convert MHTML to DOC by using save method
Load DOC file by using Document class of Aspose.Words
Save the document to DOTX format using save method and set DOTX as SaveFormat

Get Started with Java File Manipulation APIs

You can easily use Aspose.Total for Java directly from a Maven based project and include Aspose.PDF for Java and Aspose.Words for Java in your pom.xml.

Alternatively, you can get a ZIP file from downloads .

// load MHTML file with an instance of Document class
Document document = new Document("template.mhtml");
// save MHTML as a DOC 
document.save("DocOutput.doc", SaveFormat.DOC); 
// load DOC with an instance of Document
Document outputDocument = new com.aspose.words.Document("DocOutput.doc");
// call save method while passing SaveFormat.DOTX
outputDocument.save("output.dotx", SaveFormat.DOTX);   

Open Password Protected MHTML Document via Java

While converting MHTML to DOTX, even if your document is password protected, you can still open it using PDF Manipulation API Aspose.PDF for Java . In order to open the encrypted file, you need to create a Document object and open the MHTML using the owner’s password.

Document document = new Document("input.mhtml", "password");
// save MHTML as a DOC 
document.save("DocOutput.doc", SaveFormat.DOC);

Save DOTX Document to a Database via Java

While saving your input document to DOTX file format, you can also save your document to database instead of a file system. You may need to implement storing and retrieving Document objects to and from a database. This would be necessary if you were implementing any type of content management system. In order to save your DOTX to database it is often necessary to serialize the document to obtain a byte array. This can be done using Aspose.Words for Java API. After getting your byte array, you can store it in the database using SQL statement.

public static void StoreToDatabase(Document doc, Connection mConnection) throws Exception {
    // create an output stream which uses byte array to save data
    ByteArrayOutputStream aout = new ByteArrayOutputStream();
    // save the document to byte array
    doc.save(aout, SaveFormat.DOTX);
    // get the byte array from output steam
    // the byte array now contains the document
    byte[] buffer = aout.toByteArray();
    // get the filename from the document.
    String fileName = doc.getOriginalFileName();
    String filePath = fileName.replace("\\", "\\\\");
    // create the SQL command.
    String commandString = "INSERT INTO Documents (FileName, FileContent) VALUES('" + filePath + "', '" + buffer + "')";
    Statement statement = mConnection.createStatement();
    statement.executeUpdate(commandString);
}
