Convert JSON Format to ODP via C++
C++ API to parse JSON to ODP without using Microsoft® PowerPoint
Why to Convert JSON to ODP
JSON (JavaScript Object Notation) is a lightweight data-interchange format that is used to exchange data between different applications. It is a text-based format that is easy to read and write. On the other hand, ODP (OpenDocument Presentation) is an open standard for electronic documents. It is used to create presentations and is supported by many applications. Converting JSON to ODP can be useful for creating presentations from data stored in JSON format.
How Aspose.Total Helps for JSON to ODP Conversion
Aspose.Total for C++ is a suite of APIs that can be used to create, manipulate and convert documents and images. It includes APIs for manipulating documents such as Aspose.Cells for C++ and Aspose.Slides for C++. By using Aspose.Cells for C++, you can parse JSON to PPTX. After that, by using Aspose.Slides for C++, you can convert PPTX to ODP. Both APIs come under Aspose.Total for C++ package. This makes it easy to convert JSON to ODP within any C++ application in two simple steps.
Convert JSON Format to ODP via C++
- Create a new IWorkbook object and read valid JSON data from file
- Save JSON as PPTX using Save method
- Load PPTX document by using Presentation class
- Save the document to ODP format using Save method
Get Started with C++ File Automation APIs
Install via Package Manager Console of Visual Studio with Install-Package Aspose.Total.Cpp.
Alternatively, get the offline MSI installer or DLLs in a ZIP file from downloads .
Set Layout and Convert JSON Format to ODP via C++
While parsing JSON to ODP, you can also set the size of rows and columns by loading JSON with IWorkbook class. If you need to set the same row height for all rows in the worksheet, you can do it by using the SetStandardHeight method of the ICells collection. Similarly, to set the same column width for all columns in the worksheet, use the ICells collection’s SetStandardWidth method.
Convert JSON Format to ODP with Watermark in C++
Using the API, you can also convert JSON to ODP with watermark. In order to add a watermark to your ODP document, you can first parse JSON to PPTX and add a watermark to it. In order to add a watermark, load the newly created PPTX file using the Presentation class, get the first slide, Add an AutoShape of Rectangle type, add TextFrame to the Rectangle, create the Paragraph object for a text frame, create Portion object for paragraph, add watermark using set_Text() and, can save the document to ODP.
