Aspose.Total for C++ consists of powerful file automation APIs that allows to automate DOCX to PPTX conversion while using two of it’s APIs. Load your DOCX using Aspose.Words for C++ and convert it to HTML, then load the HTML via PowerPoint manipulation C++ API Aspose.Slides for C++ to create a new presentation, and save it as PPTX.
DOCX to PPTX Conversion on C++
- Open DOCX file using Document class reference
- Convert DOCX to HTML by using Save member function
- Initialize a new Presentation object
- Add an AutoShape in your slide, and add AddTextFrame in it
- Load the HTML content and write it in your Presentation file
- Save the document to PPTX format using Save method and set Pptx as SaveFormat
Get Started with C++ File Format APIs
Install from command line as
nuget install Aspose.Total.Cpp or via Package Manager Console of Visual Studio with
Alternatively, get the offline MSI installer or DLLs in a ZIP file from downloads .
// load DOCX file with an instance of Document Document document = new Document("template.docx"); System::SharedPtr<Document> doc = System::MakeObject<Document>(u"sourceFile.docx"); // save the document in HTML file format doc->Save(u"HtmlOutput.HTML"); // load the desired the presentation SharedPtr<Presentation> pres = MakeObject<Presentation>(); // access first slide SharedPtr<ISlide> sld = pres->get_Slides()->idx_get(0); // add an AutoShape of Rectangle type SharedPtr<IAutoShape> ashp = sld->get_Shapes()->AddAutoShape(ShapeType::Rectangle, 10, 10, 700, 500); // reset default fill color ashp->get_FillFormat()->set_FillType(FillType::NoFill); // add TextFrame to the Rectangle ashp->AddTextFrame(u" "); // access the text frame SharedPtr<ITextFrame> txtFrame = ashp->get_TextFrame(); // get Paragraphs collection SharedPtr<Aspose::Slides::IParagraphCollection>ParaCollection = txtFrame->get_Paragraphs(); // clear all paragraphs in added text frame ParaCollection->Clear(); // load the HTML file using stream reader SharedPtr<System::IO::StreamReader> tr = MakeObject<System::IO::StreamReader>(HtmlOutput.HTML); // add text from HTML stream reader in text frame ParaCollection->AddFromHtml(tr->ReadToEnd()); // save presentation as Pptx pres->Save(output.pptx, Aspose::Slides::Export::SaveFormat::Pptx);

Load Password Protected DOCX Document via C++
Apart from document conversion, Aspose.Words for C++ API allows tons of document manipulation features for C++ developers. In case your Microsoft Word DOCX file format is password protected, you can still open it using the API. In order to load the encrypted document, you can use a special constructor overload, which accepts a LoadOptions object. This object contains the Password property, which specifies the password string.
// when loading password protected document, the password is passed to the document's constructor using a LoadOptions object. auto options = MakeObject<LoadOptions>(u"docPassword"); // load the document from the local file system by filename: SharedPtr<Document> doc = MakeObject<Document>(u"Encrypted.docx", options);
Add Comments in PPTX Document via C++
While saving DOCX as PPTX, you can also use Aspose.Slides for C++ to add further features in your PPTX document. For instance, you can add comments in your presentation. The presentation slide comment are associated with a particular author. The Presentation class holds the collection of authors in ICommentAuthorCollection that are responsible for adding slide comments. For each author, there is a collection of comments in ICommentCollection.
// instantiate Presentation class SharedPtr<Presentation>pres = MakeObject<Presentation>(); // access first slide SharedPtr<ILayoutSlide>layout = pres->get_LayoutSlides()->idx_get(0); // add empty slide pres->get_Slides()->AddEmptySlide(layout); // adding Author SharedPtr<ICommentAuthor> author = pres->get_CommentAuthors()->AddAuthor(u"John Doe", u"MF"); // set position of comments System::Drawing::PointF point = System::Drawing::PointF(0.2f, 0.2f); // add slide comment for an author on slide 1 author->get_Comments()->AddComment(u"Hello John, this is a slide comment", pres->get_Slides()->idx_get(1), point, DateTime::get_Now()); // access ISlide 1 SharedPtr<ISlide> slide = pres->get_Slides()->idx_get(0); // save presentation as Pptx pres->Save(output.pptx, Aspose::Slides::Export::SaveFormat::Pptx);

What is DOCX File Format
DOCX is a file format for Word documents, developed by Microsoft. It is a XML-based format that allows for more complex document structures than the older DOC format, and supports features such as document encryption, digital signatures, and watermarks. DOCX files are also smaller in size than their DOC counterparts, making them more efficient to store and transmit.Read More
What is PPTX File Format
Open XML Presentation (PPTX) is a file format for storing presentations in XML format, developed by Microsoft. PPTX is a zipped, XML-based file format used for storing slide presentations. It is a successor to the PPT format and is used by Microsoft PowerPoint 2007 and later versions. The PPTX file format is based on the XML schema and uses a ZIP compression algorithm. PPTX files are stored in a folder structure, which contains a document.xml file, a slide master file, and a number of slide files. The document.xml file stores the content of the presentation, while the slide master file stores the layout and design of the slides. The slide files store the individual slides in the presentation.PPTX files can be opened in PowerPoint 2007 and later versions, as well as in some other presentation software.Read More
