Fix Malformed JSON in n8n, Zapier, and Make

🧩 Problem

AI tools and webhook payloads often return broken JSON with trailing commas, unescaped quotes, missing brackets, or code fences. When malformed or unstructured data hits routers, filters, or API connectors, entire automations halt or silently drop records. Teams end up retrying runs, hand-editing payloads, and explaining delays to customers.

πŸ’‘ Why This Happens

Automation tools do minimal JSON validation, and AI-generated content often includes formatting that isn't JSON-safe. Most automation platforms assume well-formed payloads and do minimal validation. AI models, third-party APIs, and changing vendor schemas drift over time, mixing encodings, formats, and unexpected fields that downstream steps cannot tolerate.
