AI-Driven Generation

Uses Claude Sonnet 4.5 to:

• Generate appropriate document structure
• Apply correct formatting
• Create professional, coherent content

How It Works

1. Input Form

Users provide:

• Prompt - Description of the desired document (e.g., "Generate an employment contract template")
• Logo URL - Web-accessible URL to company logo

2. Company Styling

Pre-configured branding is applied (See workflow for Description on how to Update):

• Font, font Styles (for H1,H2, ...)
• Header: Company name + logo
• Footer: Page numbers ("Page X of Y")
• Spacing rules for all content types
• Table Styles

3. AI Document Generation

The AI agent:

1. Retrieves the Json2Doc section schema
2. Generates JSON configuration for the document
3. Validates the configuration
4. Creates a document generation job
5. Returns the Job ID

4. Processing & Download

• Waits for document completion (3 seconds initially)
• Polls job status via API
• Retries if not complete
• Downloads the final DOCX file when ready

Setup Requirements

Authentication

You need a Json2Doc API key from app.json2doc.com (Permanently free version available).

Processing Times

Configuration Generation (Model-dependent)

The AI model generates the JSON configuration:

• Simple documents (1-2 pages): 10-30 seconds
• Medium documents (3-5 pages): 30-60 seconds
• Complex documents (10-20 pages): 60-120 seconds

Time varies based on the selected AI model and document complexity.

Json2Doc Processing

Once the configuration is created, Json2Doc generates the DOCX file in 2-6 seconds regardless of document size.

Extensions

This workflow can be integrated with:

• Cloud storage (Google Drive, Dropbox)
• Email services for automated delivery
• Approval workflows
• Document management systems

Important Limitation

This workflow is only suitable for documents up to 20 pages, as larger documents will exceed the AI model's context window. For longer documents, use the Builder Mode instead: DocumentBuilder Docs
