Sometimes the built-in tools may not be enough to handle your specific data transformation needs. That is where Code Runner comes in — it allows you to write your own custom Python code inside the workflow, making use of previous step results and returning transformed data.
⚠️ Warning: Always try to use the available built-in tools as much as possible before reaching for Code Runner. Using Code Runner unnecessarily may affect workflow performance.
Add a Code Runner tool. In the Inputs section, use the initialized variable:
Name
Value
orders
{{variables.orders}}
In the coding section, write the following Python code to sort the orders by amount:
sorted_orders = sorted(inputs["orders"], key=lambda x: x["amount"])
response = sorted_orders
Give title and enable Show Output in Console Log
Enable Console Logs for the workflow, save the workflow and click Sync Now. Check the logs.
Expected Output:
[
{"order_id": 3, "amount": 300},
{"order_id": 1, "amount": 500},
{"order_id": 4, "amount": 850},
{"order_id": 2, "amount": 1200}
]📌 Things to Keep in Mind:
Allowed Packages: json, datetime, math, re, time, uuid, base64, hashlib
Allowed Built-in Methods: abs, all, any, bool, dict, enumerate, filter, float, format, int, isinstance, len, list, map, max, min, range, round, set, sorted, sum, str, tuple, type, zip and all exception classes
⚠️ Note: Any packages or built-in functions outside the above list cannot be used or imported. The maximum execution time is 30 seconds.
