What problem does it solve?

This Skill helps developers harness n8n Code nodes to perform advanced data transformations, API calls, and logic directly inside workflows, reducing reliance on external scripts and consolidating automation.

Core Features & Use Cases

• Access input data with $input.all(), $input.first(), and $input.item to implement batch or per-item logic.
• Use built-in functions like $helpers.httpRequest(), DateTime (Luxon), and $jmespath() to perform API calls, date handling, and JSON querying without external packages.
• Implement robust error handling, safe null checks, and correct return formats (an array of objects with each item containing a json property).
• Use for complex data transformations, data validation, aggregation, and integration scenarios such as CRMs or dashboards.

Quick Start

Begin by reading the Quick Start example, which shows a simple transformation using $input.all() and returns [{json: {...}}].
