JSON PowerPoint - Generate PPTX files from JSON data


JSON has become a popular data format for data integration due to its simplicity and flexibility. It allows for seamless incorporation of external data into PowerPoint presentations, providing numerous benefits.

One key reason for JSON's importance in data integration is its versatility in handling a wide range of data types. JSON files can include structured data such as text, numbers, booleans, and null values, as well as more complex data structures like arrays and nested objects. This makes it compatible with various data sources, ensuring that data from different systems can be seamlessly integrated.

JSON to PowerPoint templates eliminates the need for manual data entry, saving time and reducing the risk of human errors. Instead of manually copying and pasting data into PowerPoint presentations, JSON files can be easily imported. This direct integration ensures up-to-date information, as any changes made to the external data source will be reflected automatically in the presentation.

Additionally, JSON enables dynamic and interactive presentations. JSON files can include not only static data but also interactive elements such as charts, tables, and graphs.

Building your PowerPoint through API

Building a PowerPoint presentation has never been easier with the help of EDocGen API. By utilizing API, developers can automate the process of building presentations, saving time and effort. Whether it's adding slides, populating content, or customizing the design, API provides the necessary tools for seamless integration and efficient creation of PowerPoint presentations.

Developers can use the existing PPTX template files to generate the presentations. All that is needed is to incorporate the appropriate dynamic tags to ensure the templates are prepared for API integration.

Creating new slides

To define slides in a presentation, add the tag {:slidesArray}. This creates a new slide for each record in your JSON array. You can also add the tags for images, and tables inside the slide tag. Thus, you can populate nested data structures into the PowerPoint template.

By incorporating this tag into your presentation template, you can efficiently define and structure the slides to meet your specific requirements.

To implement the loop or table tag, first identify the slide where you want the dynamic content to be inserted. Then, place the table tag within the appropriate placeholder or content box on the slide. The table tag will automatically generate output for each record in your JSON array, ensuring that all relevant information is included in the presentation.

Adding the {%imageTagName} tag in the template allows you to effortlessly display images from JSON data. This tag enables you to populate image URLs, Base64 strings, and uploaded images into the system without any hassle.


Text enclosed in curly braces represents a dynamic text field, like {Name}. This text will be replaced with JSON data during document generation.

After adding tags call the API. This is a REST API. Thus, developers can use a programming language of their choice.

How to convert JSON to PowerPoint through UI

To convert JSON to PPT, follow these simple steps:

Step1: Upload Template

After adding tags to your template, upload it to the system.

Step2: XML to PowerPoint Generation

To generate the document, click on the "Generate" button. This will open the document generation options pop-up. Choose the "Upload data" option. You then simply upload the XML data without needing to make any expensive data transformations.

JSON to PowerPoint

If you're generating multiple documents from your XML, you'll find them in a zip file. Otherwise, the system will create a single PPT file. You can download the generated files from the output folder.

By following these steps, you can effortlessly convert JSON to PPTX. This hassle-free process ensures that you can easily present your JSON data in an engaging and visually appealing PowerPoint presentation format.

The generated files can be distributed through multiple channels, such as saving them to cloud storage, sending them via email, or using e-Sign. The system offers out-of-box integrations with OneDrive, SharePoint, AWS S3 bucket.
