Convert a Document in Java

The ability to quickly, reliably and efficiently save a file into different formats with a high degree of precision is the reason most of our customers choose Aspose.Words.

Java API allows you to convert a file from one supported format to another with just two lines of code. It is so simple!

// Load DOC file to be converted
Document wpd = new Document(dir + "template.doc");

// Convert DOC to DOCX
wpd.save(dir + "output.docx", SaveFormat.DOCX);

// Load HTML file to be converted
Document wpd = new Document(dir + "template.html");

// Convert HTML to DOCX
wpd.save(dir + "output.docx", SaveFormat.DOCX);

// Load RTF file to be converted
Document wpd = new Document(dir + "template.rtf");

// Convert RTF to PDF
wpd.save(dir + "output.pdf", SaveFormat.PDF);

See more details on the Conversion page.

On the documentation pages you can find out how to:

• convert document pages to images for preview
• convert a document to PDF or PDF/A
• manage fonts and font substitutions
• print the documentc programmatically or using dialogs
• and so on

Reporting and Mail Merge

Aspose.Words for Java is a full featured reporting solution. You can design reports in Microsoft Word and then allow the API to populate files with data from a variety of data sources while keeping the mail merge settings preserved.

Aspose.Words for Java allows you to use standard Microsoft Word mail merge fields in reports. Additionally, you can use library extended syntax for mail merge fields to perform more complex tasks during the merging operations such as inserting images or repeatable regions.

Programming with Documents Using Document Object Model (DOM)

Aspose.Words for Java helps developers to create, build, modify, parse and examine loaded files using our intuitive Document Object Model (DOM) that consists of over 100 classes. This object model allows developers to programmatically manipulate various elements such as Sections, Headers, Footers, Paragraphs, Lists, Tables, Text, Fields, Hyperlinks, Bookmarks, Images, Smart tags, Shapes, Custom XML and more.

Furthermore, all drawing objects, including shapes, text boxes, images, OLE objects and controls are supported through this document object model, allowing you to perform many tasks such as inserting watermarks on pages or extracting images from a pre-existing file.

Aspose.Words for Java provides useful utility features, for example, join or split files, find and replace text, protect or unprotect files, modify properties and insert HTML fragments into documents. All of these features are available via easy-to-use APIs to help developers perform complex operations without worrying about the file format specifications.

// Load source & destination files
Document srcDoc = new Document(dir + "source.docx");
Document dstDoc = new Document(dir + "destination.docx");

// Set the appended file to start from a new page
srcDoc.getFirstSection().getPageSetup().setSectionStart(SectionStart.NEW_PAGE);

// Append the source file using its original styles
dstDoc.appendDocument(srcDoc, ImportFormatMode.KEEP_SOURCE_FORMATTING);

// Save final result
dstDoc.save(dir + "output.docx");

No Need for Microsoft Office Automation

You can work with documents programmatically without installing any other third-party application. This is possible because the library is built using managed code. Therefore, you do not need to install Microsoft Office or Microsoft Word on your computer to work with Word formats. It is a perfect alternative to Microsoft Office Automation in terms of supported features, security, stability, scalability, speed, and price.
