Transform EPUB to MARKDOWN via Java
On Premise Java API to Render EPUB to MARKDOWN without using any third party application
You can convert EPUB to MARKDOWN by using two simple steps. First you need to render EPUB file to DOC using Aspose.PDF for Java . After that, by using powerful Document Processing API Aspose.Words for Java , you can convert DOC to MARKDOWN. Both APIs come under Aspose.Total for Java package.
Java API to Convert EPUB to MARKDOWN
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.MARKDOWN
outputDocument.save("output.markdown", SaveFormat.MARKDOWN);
Open Password Protected EPUB Document via Java
While converting EPUB to MARKDOWN, 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 MARKDOWN Document to a Database via Java
While saving your input document to MARKDOWN 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 MARKDOWN 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.MARKDOWN);
// 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 MARKDOWN File Format?
Markdown, a lightweight markup language widely utilized for creating formatted documents and web content, offers a user-friendly and efficient solution. With its straightforward syntax, Markdown allows users to quickly learn and apply it for various purposes. Its versatility is a key advantage, as it accommodates the creation of simple notes, to-do lists, as well as complex technical documentation and web pages. Moreover, Markdown provides flexibility by enabling easy conversion to other formats, including HTML, PDF, and DOCX, enhancing its portability.
Simplicity is another valuable aspect of Markdown. By employing a minimal syntax, it allows users to focus on the content of their documents rather than grappling with intricate formatting rules. This simplicity facilitates swift and efficient content creation, eliminating the need to dwell on formatting minutiae. Markdown also boasts compatibility with numerous tools and platforms, making it highly accessible. Notion, Obsidian, and Bear are just a few examples of popular writing and note-taking applications that support Markdown. Furthermore, Markdown files can be effortlessly shared and collaborated on through version control systems like Git, streamlining collaborative workflows.
