AI JSON Generation with Validation & Refinement

# AI-powered JSON schema generation with validation and refinement in n8n

This workflow automatically generates and refines JSON schemas from text descriptions using an AI agent powered by Mistral Cloud and LangChain. The process includes schema creation, correctness validation, and applicability testing, with iterative loops until success or attempt limit is reached. Designed for standardizing data interchange formats across AI services.

## Who it´s for
- AI agent developers needing standardized JSON input/output formats
- Data engineers automating cross-system data exchange
- Tech leads designing ML application architectures
- Automation specialists using n8n for complex data workflows

## What the automation does
- Accepts a text description via manual trigger
- Generates initial JSON structure using Mistral Cloud and LangChain
- Validates schema correctness via custom output parser and AI agent
- Tests format applicability against real-world use cases
- Repeats cycle until valid schema is produced or attempts are exhausted
- Outputs final usable JSON structure

## What´s included
- Ready-to-use n8n workflow
- Trigger and handler logic
- Integrations with Mistral Cloud API and custom node (n8n-nodes-advanced-output-parser)
- Basic setup and adaptation guide

## Requirements for setup
- n8n instance (self-hosted or cloud)
- Active Mistral Cloud API access with valid keys
- Installed custom node: n8n-nodes-advanced-output-parser
- Understanding of JSON, AI agents, and LangChain concepts

## Benefits and outcomes
- Reduces time spent on manual JSON schema design
- Ensures consistency across AI service interfaces
- Enables iterative improvement without manual intervention
- Produces database-ready or system-compatible JSON structures
- Automated validation and testing via AI agent loop
- Repeatable process for diverse data types and tasks
