n8n-code-python

What problem does it solve?

n8n code-python enables writing Python logic inside the Code node, while respecting the no-external-libraries limit and leveraging the standard library to perform data transformations, webhook payload handling, and batch processing.

Core Features & Use Cases

• Safe data access patterns with _input.all(), _input.first(), and _input.item to build robust workflows.
• Standard library focused tasks: JSON handling, datetime calculations, regex parsing, and basic data transformations without external dependencies.
• Real-world use cases include aggregating values from multiple items, validating and transforming webhook payloads, and per-item enrichment in a Run Once for Each Item mode.

Quick Start

• Create a Python Code node, import only the standard library, and access incoming data via _input.all() or _input.first().
• Return results using the required format: a list of dictionaries each containing a "json" key, e.g., [{"json": {"processed": true}}].
• Example: compute total from all items and return {"total": total, "count": len(all_items)}.
