Rename Keys Data Transformation

This workflow automates JSON key renaming via webhook, replacing manual data munging in scripts or tools that take 5-10 minutes per batch for developers. The Webhook receives POST payloads, the Input Validation Set extracts body, the Check Input Valid If routes, the Rename Keys node transforms 'toBeRenamed' to 'Renamed', the Validation Function verifies, and Success Response returns updated JSON. Errors (Error Response) handle invalid inputs. It helps backend devs in small app teams (5-20 staff) normalizing 100+ payloads weekly, ensuring consistent schemas without custom code, streamlining ETL or API integrations.\n\nThis workflow saves 2-3 hours weekly on 100 transformations, boosting reliability by 95%. Use cases include data pipeline normalization for startups, payload formatting for agencies. Suitable for small-mid teams. Requires n8n (free self-hosted or $20/month cloud). Scalable to 500 requests/day with cloud tiers.\n\nInstall n8n via n8n.io or cloud.n8n.io. No external services needed. Import JSON, configure Webhook POST 'rename-keys'. Update Rename Keys with custom mappings. Webhook URL: https://your-n8n-instance/webhook/rename-keys.\n\nTest with Postman: {toBeRenamed: 'value'}. Verify renamed in response. Errors: Invalid body (400). Activate webhook. Monitor dashboard weekly.
