Test it
Using "n8n-code-python". Normalize webhook contacts and mark records that lack an email address.
Expected outcome:
A batch transformation reads the webhook body, standardizes contact fields, and attaches validation messages to incomplete records.
Using "n8n-code-python". Calculate sales totals and averages for active records.
Expected outcome:
- Inactive records are excluded before calculation.
- The result includes total sales, active record count, and average sales.
- Empty input produces zero values without division errors.
Using "n8n-code-python". Explain why a Python Code node fails after importing requests.
Expected outcome:
The review identifies an unsupported external package and recommends an HTTP Request node before the Python transformation.

What You Can Build
Transform Workflow Items
Create a Code node that cleans, maps, and enriches incoming records while preserving n8n output structure.
Summarize Operational Data
Filter records and calculate totals, counts, averages, or basic statistics without external packages.
Repair Failing Code Nodes
Diagnose input access, webhook nesting, missing keys, unsupported imports, and invalid return formats.
Try These Prompts
Create a Basic Transformation
Write an n8n Python Code node that reads all items, maps [fields], adds [new field], and returns the required structure.
Normalize Webhook Data
Create Python for an n8n webhook workflow. Read fields from the body safely, normalize [fields], and report missing values.
Validate and Aggregate Records
Build an n8n Python Code node that validates [rules], separates invalid records, and calculates [metrics] from valid records.
Design an Advanced Processing Step
Review this n8n processing requirement: [requirement]. Select the execution mode, design robust Python logic, and explain limitations and edge cases.
Best Practices
- Test with empty, incomplete, and representative input before deploying the workflow.
- Use safe dictionary access and explicit defaults for optional fields.
- Choose all-items mode for batch work and return a consistent n8n item structure.
Avoid
- Do not import external packages that the n8n Python runtime does not provide.
- Do not return plain values or dictionaries without the required item wrapper.
- Do not assume webhook fields exist at the top level or are always present.
Frequently Asked Questions
Which n8n Python mode should I use?
Use Python Beta for n8n helpers. Use Native mode only when pure Python variables meet the requirement.
Can the Code node import pandas or requests?
No. The documented runtime supports standard-library modules, so use dedicated n8n nodes for HTTP or specialized processing.
How should Python Code nodes return data?
Return a list of n8n items. Each item must contain a json field holding its output data.
Where is webhook payload data located?
Webhook payload fields are normally under the body field. Use safe access because fields may be absent.
Can this skill process multiple input items?
Yes. It covers batch processing, filtering, transformations, aggregations, and per-item execution.
Does the generated code still need testing?
Yes. Test it with actual node data, edge cases, and the Python runtime available in your n8n installation.
