Convert JSON Arrays to CSV for Reports

🧩 Problem

Reporting tools and spreadsheets prefer CSV, but webhooks send nested JSON arrays. 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

APIs optimize for JSON, leaving you to reshape data for CSV imports. 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.
