JSON to CSV for Marketing Lead Uploads

🧩 Problem

Marketing platforms prefer CSV uploads; webhooks deliver JSON. 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.

💡 Why This Happens

Lead gen tools emit JSON; imports want CSV. 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.
