How to save CrewAI output to file

Quick answer

Use Python's file handling to save CrewAI output by capturing the response string and writing it to a file with open(). After calling CrewAI's API, write the output text to a file using file.write().

PREREQUISITES

Python 3.8+
CrewAI API key
pip install crewai-sdk (or relevant SDK)
Basic knowledge of Python file I/O

Setup

Install the CrewAI SDK and set your API key as an environment variable for secure access.

bash

pip install crewai-sdk

# In your shell or environment setup
export CREWAI_API_KEY=os.environ["CREWAI_API_KEY"]

Step by step

This example shows how to call CrewAI's text generation and save the output to a local file named output.txt.

python

import os
from crewai import CrewAIClient

# Initialize client with API key from environment
client = CrewAIClient(api_key=os.environ["CREWAI_API_KEY"])

# Generate text from CrewAI
response = client.generate_text(prompt="Write a short poem about spring.")

# Extract the generated text
output_text = response.text

# Save output to file
with open("output.txt", "w", encoding="utf-8") as file:
    file.write(output_text)

print("CrewAI output saved to output.txt")

output

CrewAI output saved to output.txt

Common variations

Use open("output.txt", "a") to append instead of overwrite.
Save JSON output by serializing response if it contains metadata.
Use async SDK methods if supported for non-blocking calls.

Troubleshooting

If you get a FileNotFoundError, ensure the directory exists or use an absolute path.
If the API key is invalid, verify CREWAI_API_KEY is set correctly in your environment.
Check for network issues if the API call fails.

✅

Key Takeaways

Always retrieve your CrewAI API key securely from environment variables.
Use Python's built-in open() and write() to save AI output to files.
Appending to files allows you to keep logs of multiple AI outputs.
Check file paths and permissions to avoid common file I/O errors.
Consider serializing full API responses if you need metadata along with text.
