High-Volume JSON to PDF Document Generation
Send JSON. Get a compliant PDF back. MHC NorthStar CCM’s REST API accepts JSON data, applies rules-based composition for regulated content, adds AI-powered personalization, and returns a production-ready PDF. Batch or on-demand. 300+ pages per second.
JSON to PDF Document Generation with MHC NorthStar CCM
MHC NorthStar CCM generates PDF documents from JSON data via its REST API. Your application sends a JSON object containing the data fields and template identifier. The rules engine evaluates conditional logic based on the JSON data and assembles the correct content blocks to produce a compliant PDF.
Two generation modes: real-time (POST JSON, receive PDF in response) and batch (multiple JSON objects processed in a single run, hundreds of thousands of PDFs). Both use the same templates and rules engine. JSON and XML are both supported — same templates work with either format.
Beyond PDF, the same template composition produces email, HTML, XML, and print-ready output delivered across channels based on customer preferences.
How To Convert JSON to PDF
JSON contains primarily data, therefore it makes sense to have some layout information such as fonts or colors defined somewhere. This is information can be defined in a layout template. The template describes how data will be presented into a human readable format.
The template also contains a set of rules that apply when generating the output, such as fields, dynamic tables, conditions or conditional expressions. Once you have designed your template, you can then use the MHC API to generate PDF, Microsoft® Word or even interactive HTML5 documents.
MHC provides a truly enterprise solution, suitable for the most complex business uses while providing and easy to use environments available today. Click Play for a quick introduction.
1.
Design a template using MHC
Design a template using MHC Studio, our visual design environment. While the user interface is similar to popular Office programs (in order to minimize the learning curve for business users and developers aline), the Studio provides all the features need to work with the most complex JSON data using simple drag & drop operations.
2.
Use the MHC API to convert JSON to PDF
Use the MHC API to convert JSON to Microsoft® Word, PDF or any other supported output formats. The template you have designed in the first step can also be used to generate JPEG, PowerPoint, Interactive HTML5 and more. In addition, your JSON can be processed in real-time or in an asynchronous fashion.
Output Formats
Same JSON. Multiple Outputs.
One template, every format your application needs.
Standard, PDF/A, Accessible
Email (HTML)
HTML with preference management
HTML / XML
Web and data interchange
Page control, batch support
HOW IT WORKS
REST API. Two Modes. One Architecture.
Real-Time / On-Demand
POST your JSON to the REST endpoint. Rules engine evaluates conditions. AI Assist personalizes narrative sections. Response returns the PDF. Supports preview before final generation.
POST /api/generate
Content-Type: application/json
Body: { “template”: “…”, “data”: {…} }
→ 200 OK
→ Content-Type: application/pdf
Batch / Bulk Mode
Submit an array of JSON objects. Scales to hundreds of thousands per run. Throttling protects interactive performance. Errors logged per document; processing continues.
Input: 100,000 JSON objects
Processing: 300+ pages/sec
Output: 100,000 PDFs
→ Failed docs logged
→ Processing continues
Capabilities
What You Can Do with JSON to PDF
● Precision
Conditional Content from JSON Fields
JSON field values drive which content blocks appear. Jurisdiction, product, coverage, and customer attributes determine exact regulated language. Deterministic rules, not AI.
● Precision
Dynamic Tables from JSON Arrays
Iterate over JSON arrays for repeating rows, line items, and variable-length content. Expressions support computed values, substrings, and counters.
● Intelligence
AI-Assisted Templates
AI Assist drafts templates from prompts, refines content, translates 60+ languages. AI operates on the intelligence layer only. Regulated content stays rules-governed.
● Precision
Multi-Language Output
A language field in your JSON drives language-specific content, images, and components. One template, all languages.
● Both
Images and Subdocuments
Embed JPG, PNG, GIF, SVG, PDF. Base64-encoded subdocuments in JSON decoded and embedded automatically.
● Precision
Page Control and Print
Page breaks, section grouping, recto/verso. Print-ready PDFs with full pagination control.
● Both
Barcode Generation
QR codes and Data Matrix barcodes. Content populated from JSON fields.
● Precision
Real-Time Preview
Preview before committing. Test against sample JSON to verify every conditional path.
● Both
No-Code Designer
WYSIWYG graphical designer. No programming. Screen matches final PDF. Version control supported.
Interactive Code Samples
Try Our APIs for Yourself
We’ve prepared code samples showcasing how to convert XML, JSON, and XSL-FO to PDF using stored templates, as well as how to merge multiple documents into a single PDF. Get in touch with our tech team to explore these examples and see how easily you can integrate with MHC.
Convert XML to PDF
The code sample uses the API to convert XML to PDF using a stored template. An XML string is sent to MHC server and a PDF is received back.
Convert JSON to PDF
The code sample uses the API to convert JSON to PDF using a stored template . A JSON is sent to MHC server and a PDF is received back.
Convert XSL-FO to PDF
The code sample uses the API to convert XSL-FO to PDF. An XSL-FO string is sent to MHC server and a PDF file is received back.
Merge Multiple Documents
The code sample uses the API to merge a document package stored on the server to a single PDF file.

Frequently Asked Questions
JSON to PDF with MHC NorthStar CCM
How do I generate a PDF from JSON data?
Send a POST request to MHC NorthStar CCM’s REST API with a JSON object containing data fields and template identifier. The rules engine evaluates conditional logic, assembles compliant content, and returns the PDF. AI Assist personalizes narrative sections. Both JSON and XML input supported.
What is the best JSON to PDF API?
Lightweight: PDFMonkey, CraftMyPDF, Carbone.io, Adobe PDF Services. Full CCM for regulated industries: MHC NorthStar CCM, Quadient Inspire, OpenText Exstream. CCM platforms add rules-based composition, AI, omnichannel delivery, and compliance workflows that standalone converters do not.
Can I batch generate PDFs from JSON?
Yes. Multiple JSON objects per run. 300+ pages/sec. Hundreds of thousands of PDFs. Errors logged per document; processing continues. No impact on interactive performance.
Does it support XML too?
Yes. Same API, same templates, same logic. JSON or XML — whichever your systems produce.
How does conditional logic work?
JSON field values determine content. Jurisdiction, product, coverage, customer attributes drive which regulated blocks appear. Deterministic rules, not AI. JSON arrays generate dynamic tables. Expressions support computed values.
