Converting an EPUB file to ODT is a simple two-step process. The first step is to render the EPUB file to DOC using Aspose.PDF for Java. Aspose.PDF for Java is a powerful PDF processing API that is part of the Aspose.Total for Java package. It allows you to easily convert EPUB files to DOC format.
Once the EPUB file has been rendered to DOC, the second step is to convert the DOC file to ODT using Aspose.Words for Java. Aspose.Words for Java is a powerful document processing API that is also part of the Aspose.Total for Java package. It allows you to quickly and easily convert DOC files to ODT format.
By using Aspose.PDF for Java and Aspose.Words for Java, you can easily convert EPUB files to ODT format in just two simple steps. Aspose.PDF for Java allows you to render EPUB files to DOC format, and Aspose.Words for Java allows you to convert DOC files to ODT format. Both APIs are part of the Aspose.Total for Java package, making it easy to access both APIs in one convenient package.
Java API to Convert EPUB to ODT
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 EPUB file with an instance of Document class
Document document = new Document("template.epub");
// save EPUB 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.ODT
outputDocument.save("output.odt", SaveFormat.ODT);
Open Password Protected EPUB Document via Java
While converting EPUB to ODT, 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 EPUB using the owner’s password.
Document document = new Document("input.epub", "password");
// save EPUB as a DOC
document.save("DocOutput.doc", SaveFormat.DOC);
Save ODT Document to a Database via Java
While saving your input document to ODT 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 ODT 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.ODT);
// 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);
}

What is EPUB File Format?
An EPUB file, also known as an Open eBook File, is a standardized format developed by the International Digital Publishing Forum (IDPF). It is based on XML (eXtensible Markup Language) and XHTML (eXtensible Hypertext Markup Language). EPUB files are designed for reading digital books and publications on various electronic devices such as e-readers, tablets, and smartphones.
EPUB files consist of three main components. The first component is the spine, which contains the main text of the book and defines the order in which the pages should be read. It provides the structural framework for the content.
The second component is the manifest, which serves as a catalog of all the files that make up the EPUB book. This includes the spine, cover image, table of contents, and any additional content. The manifest ensures that all the necessary files are properly linked and organized within the EPUB package.
The third component is the container, which stores the EPUB files in a compressed format. The container helps reduce file size and enables efficient distribution and storage of EPUB books.
EPUB files can be created using various software programs such as Adobe InDesign, Sigil, and Calibre. These tools provide authors and publishers with the ability to create, edit, and format EPUB books according to the specifications set by the IDPF. With EPUB being an open and widely adopted standard, readers can enjoy a seamless reading experience across different devices and platforms.
What is ODT File Format?
ODT is a file format used for storing documents in the Open Document Format (ODF). ODT stands for Open Document Text. It is the default file format for word processing documents created by applications such as LibreOffice, OpenOffice, and Apache OpenOffice.
ODT files are based on XML, which is a markup language used for organizing and structuring data. They are designed to be an open and interoperable format, allowing users to create, edit, and share documents across different software applications and platforms.
The ODT format supports a wide range of features and formatting options commonly found in word processing documents. It includes support for text styling, paragraphs, tables, images, hyperlinks, headers and footers, footnotes, and more. ODT files can also contain embedded objects and multimedia elements.
One of the key advantages of the ODT format is its compatibility with different software applications. Users can create an ODT document in one word processing application and open it in another without losing formatting or content. This promotes collaboration and ensures that documents can be accessed and edited by users who may be using different software.
ODT files can be easily converted to other popular document formats, such as Microsoft Word’s DOCX format or PDF, for wider compatibility and sharing purposes. Additionally, the ODT format is designed to be future-proof, allowing for long-term preservation and accessibility of documents.
