Set Layout and Convert JSON Format to OTP via Java

Furthermore, the API allows you to parse JSON to OTP with specified layout options. In order to specify the layout options, you can use JsonLayoutOptions class. It allows you to process an array as a table, ignore nulls, ignore array title, ignore object title, convert string to number or date, set date and number format, and set title style. All of these options allow you to present your data as per your needs. The following code snippet shows you how to set the layout options.

Convert JSON Format to OTP with Watermark via Java

Using the API, you can also convert JSON to OTP with watermark. In order to add a watermark to your OTP 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, loop through all slides, add text using addTextFrame, set all the relevant options like color, fillType and more and can save the document to OTP.

Converting **JSON to OTP** is crucial for generating **presentation templates** from structured datasets. OTP, the OpenDocument Presentation Template format, enables organizations to create reusable, standardized templates compatible with LibreOffice Impress and other open-source office suites. By transforming JSON into OTP, enterprises, governments, and educators can streamline slide creation, maintain consistent branding, and ensure open-standard compliance.

Key Use Cases

Enterprise slide templates – Generate corporate-ready templates for consistent business presentations.
Educational frameworks – Automate slide structures for lectures, seminars, and eLearning modules.
Departmental branding – Ensure uniform templates for internal and external communication.
Government-approved templates – Standardize official presentations across departments.
Academic lecture slides – Simplify template-driven presentation creation for research and teaching.

Automation Scenarios

JSON-to-OTP pipelines – Automate template creation directly from structured data.
Automated template generation – Reduce manual formatting effort while ensuring consistency.
JSON-driven presentation standardization – Enforce compliance with enterprise or institutional branding.
Cloud-ready template distribution – Enable seamless sharing of OTP templates across teams and systems.
