Converting a YAML file to JSON object in Python

Converting a YAML file to JSON object in Python

To convert a YAML file to a JSON object in Python, you can use the PyYAML library to parse the YAML file and the json module to convert the parsed data into a JSON object. Here is a step-by-step guide on how to achieve this:

  1. Install PyYAML if you haven't already. You can install it using pip:

    pip install pyyaml

  2. Read the YAML file and convert it to a JSON object.

Here's a complete example:

import yaml import json # Load the YAML file with open('example.yaml', 'r') as yaml_file: yaml_content = yaml.safe_load(yaml_file) # Convert the YAML content to a JSON string json_content = json.dumps(yaml_content, indent=4) # Print the JSON content print(json_content) # Optionally, if you want to save the JSON content to a file with open('output.json', 'w') as json_file: json_file.write(json_content)

Explanation:

  1. Import Libraries:

    import yaml import json

  2. Load YAML File:

    with open('example.yaml', 'r') as yaml_file: yaml_content = yaml.safe_load(yaml_file)
    • This reads the YAML file and parses it into a Python dictionary using yaml.safe_load().

  3. Convert to JSON:

    json_content = json.dumps(yaml_content, indent=4)
    • This converts the Python dictionary to a JSON string. The indent=4 parameter is optional and makes the JSON output pretty-printed with an indentation of 4 spaces.

  4. Print JSON Content:

    print(json_content)

  5. Save JSON Content to File (Optional):

    with open('output.json', 'w') as json_file: json_file.write(json_content)

Example YAML File (example.yaml):

name: John Doe age: 30 is_employee: true skills: - Python - Data Analysis - Machine Learning address: street: 1234 Elm Street city: Springfield state: IL postal_code: 62701

Example Output (output.json):

{ "name": "John Doe", "age": 30, "is_employee": true, "skills": [ "Python", "Data Analysis", "Machine Learning" ], "address": { "street": "1234 Elm Street", "city": "Springfield", "state": "IL", "postal_code": 62701 } }

This script reads the YAML content from example.yaml, converts it to a JSON string, prints the JSON string, and optionally writes it to output.json.
