Generating PDF/UA from Word templates

Markdown version of this page, suitable for AI agents and automation

Organizations use template processing to generate consistent documents at scale while meeting accessibility requirements. This guide shows how to process a Word template with dynamic data and convert the result to PDF/UA.

Use this workflow to generate contracts, reports, invoices, or similar standardized documents. The process keeps document structure and branding consistent while producing accessible output.

PDF/UA (Universal Accessibility) supports accessibility requirements for standards and policies such as Section 508, ADA, and EN 301 549.

Prepare the project

Initialize licensing before you process templates or convert documents:

using GdPicture14;


LicenseManager license = new LicenseManager();
license.RegisterKEY(""); // Set your license key

Set up template processing

Create a GdPictureOfficeTemplater instance and load the JSON data model:

GdPictureOfficeTemplater templater = new GdPictureOfficeTemplater();


templater.SetTemplate(System.IO.File.ReadAllText("input_template_model.json"));

The templater uses JSON values to replace placeholders in the Word template.

Load and process the template document

Process the template in three steps.

Step 1 — Load the template 

templater.LoadFromFile(@"input_template.docx");

LoadFromFile reads the template document into memory.

Step 2 — Process template markers 

templater.Process();

Process resolves placeholders using the JSON model and preserves document formatting and layout.

Step 3 — Save the processed DOCX 

templater.SaveToFile(@"output.docx");

SaveToFile writes the processed result as a new Word document.

Convert to PDF/UA

Convert the processed DOCX to PDF/UA:

using GdPictureDocumentConverter converter = new GdPictureDocumentConverter();


converter.LoadFromFile(@"output.docx");


converter.SaveAsPDF(@"output.pdf", PdfConformance.PDF_UA_1);

Key features

  • Template-driven document generation with Word and JSON
  • Dynamic placeholder replacement
  • PDF/UA output for accessible documents
  • Formatting and style preservation from the source template
  • Support for high-volume generation workflows
  • DOCX input with accessible PDF output

Conclusion

This guide covers a full workflow for template-driven document generation with accessible output. You process a Word template with JSON data and convert the result to PDF/UA, so generated documents stay consistent and accessibility-ready.
