Convert JSON Format to POTM via C++
C++ API to parse JSON to POTM without using Microsoft® PowerPoint
Why to Convert JSON to POTM
JSON (JavaScript Object Notation) is a lightweight data-interchange format that is used to store and exchange data. It is a text-based format and is easy to read and write. POTM (PowerPoint Open XML Macro-Enabled Presentation) is a file format used by Microsoft PowerPoint. It is a macro-enabled version of the PPTX file format and is used to store presentations that contain macros. Converting JSON to POTM is useful for creating presentations with macros from JSON data.
How Aspose.Total Helps for JSON to POTM Conversion
Aspose.Total for C++ is a suite of APIs that enables developers to create, manipulate, convert, and render documents within any C++ application. It includes APIs for manipulating documents of various formats, including JSON, PPTX, and POTM. With Aspose.Total for C++, you can easily convert JSON to POTM within any C++ application in two simple steps.
Firstly, by using Aspose.Cells for C++, you can parse JSON to PPTX. Aspose.Cells for C++ is a powerful spreadsheet processing API that enables developers to create, manipulate, convert, and render spreadsheets within any C++ application. It supports a wide range of spreadsheet formats, including JSON, and can be used to convert JSON to PPTX.
After that, by using Aspose.Slides for C++, you can convert PPTX to POTM. Aspose.Slides for C++ is a powerful presentation processing API that enables developers to create, manipulate, convert, and render presentations within any C++ application. It supports a wide range of presentation formats, including PPTX and POTM, and can be used to convert PPTX to POTM.
Both Aspose.Cells for C++ and Aspose.Slides for C++ come under the Aspose.Total for C++ package. Aspose.Total for C++ is a comprehensive suite of APIs that enables developers to create, manipulate, convert, and render documents within any C++ application. It includes APIs for manipulating documents of various formats, including JSON, PPTX, and POTM. With Aspose.Total for C++, you can easily convert JSON to POTM within any C++ application in two simple steps.
Convert JSON Format to POTM 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 POTM 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 POTM via C++
While parsing JSON to POTM, 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 POTM with Watermark in C++
Using the API, you can also convert JSON to POTM with watermark. In order to add a watermark to your POTM 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 POTM.

What is JSON File Format?
The JSON (JavaScript Object Notation) file format is a lightweight and widely used data interchange format. It was derived from the JavaScript programming language but is now language-independent and supported by various programming languages. JSON files store data in a structured and readable format, making them easy to understand and process by both humans and machines.
JSON files consist of key-value pairs organized in a hierarchical structure. They represent data in a simple and intuitive way using objects (enclosed in curly braces {}) and arrays (enclosed in square brackets []). Each key is paired with a corresponding value, which can be a string, number, boolean, null, object, or array. This flexibility allows JSON to handle complex and nested data structures.
One of the main advantages of JSON is its simplicity and ease of use. Its lightweight nature and minimal syntax make it efficient for data transmission over networks and storage in files. JSON files are commonly used for data exchange between web servers and clients, as well as for configuration files, APIs, and storing structured data.
JSON files are human-readable and can be easily understood and modified using a text editor. They are also machine-readable, allowing applications to parse and process JSON data efficiently. Many programming languages provide built-in libraries or packages for working with JSON, simplifying the parsing and serialization of JSON data.
What is POTM File Format?
POTM is a file format used in Microsoft PowerPoint to store presentation templates that also include macros. Similar to the POTX format, POTM files are part of the Office Open XML (OOXML) format introduced in PowerPoint 2007.
The “M” in POTM stands for macros, indicating that these templates can contain VBA (Visual Basic for Applications) code that automates tasks and enhances the functionality of the presentation. This allows users to create dynamic and interactive templates that go beyond static design elements.
POTM files offer the same benefits as POTX files in terms of providing pre-designed slide layouts, formatting, and styles. However, the inclusion of macros adds an extra layer of interactivity and automation to the templates. Macros can perform tasks such as data manipulation, calculations, slide transitions, and user interactions, making presentations more engaging and efficient.
To use a POTM file, users can open it in PowerPoint or select it as a template when creating a new presentation. The macros embedded in the POTM template can be executed and interacted with during the presentation, providing enhanced functionality beyond what is possible with a standard template.
It’s important to note that due to security concerns, some systems and organizations may have restrictions on running macros in PowerPoint presentations. In such cases, users may need to adjust their security settings or obtain necessary permissions to enable the execution of macros in POTM files.
POTM files are compatible with different versions of PowerPoint on various platforms, allowing users to create and share templates with macros across different devices and environments. They provide a powerful tool for creating interactive and automated presentations, offering greater flexibility and customization options for users.
