Reliable AI Agent JSON Output with OpenAI Validation Loop
Achieves reliable structured JSON from AI Agents using OpenAI and a custom validation loop, bypassing unreliable Structured Output Parser.
This n8n workflow provides a robust alternative to the Structured Output Parser for extracting JSON-formatted data from AI Agents. It processes inputs like food items to output nutritional values in a precise schema, using OpenAI's GPT-4.1-nano by default. A custom loop with schema validation ensures output reliability without the common failures of parser nodes.
The workflow operates via a manual validation process: after the AI Agent responds, a schema check verifies JSON structure. A Switch
