ConfigConverter

ConfigConverter is a powerful and easy-to-use tool designed to convert configuration files between various formats, including JSON, YAML, TOML, INI, and XML.

Features

• Multi-Format Support: Seamlessly convert between JSON, YAML, TOML, INI, and XML formats.
• Command-Line Interface (CLI): Perform conversions directly from your terminal with simple commands.
• Python API: Integrate conversion functionality into your Python projects effortlessly.
• Extensible and Customizable: Easily extend the tool to support additional formats or custom conversion logic.
• User-Friendly: Intuitive design ensures a smooth experience for both beginners and advanced users.

Installation

Via PyPI

Install ConfigConverter using pip:

pip install configconverter

From Source

Clone the repository and install using Poetry:

git clone https://github.com/ankit-aglawe/configconverter.git
cd configconverter
poetry install

Quick Start

Command-Line Usage

Convert config.json to config.yaml:

configconverter config.json config.yaml

Specify input and output formats explicitly:

configconverter -i ini -o toml settings.conf settings.toml

Output the converted configuration to standard output:

configconverter config.toml -o json --stdout

Python API Usage

Convert Using File Paths

from configconverter import convert

# Convert JSON to YAML and save to a file
convert('config.json', 'json', 'yaml', output_file='config.yaml')

Convert Using Data Strings

from configconverter import convert

# Convert JSON string to YAML string
json_data = '{"name": "John", "age": 30}'
yaml_data = convert(json_data, 'json', 'yaml', from_file=False)
print(yaml_data)

Examples

Batch Conversion

Convert all JSON files in a directory to YAML:

import os
from configconverter import convert

input_dir = 'json_configs'
output_dir = 'yaml_configs'
os.makedirs(output_dir, exist_ok=True)

for filename in os.listdir(input_dir):
    if filename.endswith('.json'):
        input_file = os.path.join(input_dir, filename)
        output_file = os.path.join(output_dir, filename.replace('.json', '.yaml'))
        convert(input_file, 'json', 'yaml', output_file=output_file)

Custom Indentation

Convert a file with custom indentation:

configconverter config.json config.yaml --indent 2

Handling Complex Data Structures

When dealing with configurations that contain complex nested structures or special data types, consider the following:

• Avoid Incompatible Formats: As INI format does not support nested structures, avoid converting complex configurations to INI.

• Custom Serialization: If you must convert to a format with limitations, consider serializing complex data types into strings using JSON serialization.

• Example:

  import json
  from configconverter import convert
  
  # Serialize complex data to JSON strings before conversion
  def serialize_complex_data(data):
      if isinstance(data, (dict, list)):
          return json.dumps(data)
      return data
  
  # Custom converter function
  def custom_convert(input_file, output_file):
      with open(input_file, 'r') as f:
          data = json.load(f)
  
      # Serialize complex data
      for key, value in data.items():
          data[key] = serialize_complex_data(value)
  
      # Convert to INI
      convert(data, 'json', 'ini', output_file=output_file, from_file=False)
  
  custom_convert('complex_config.json', 'config.ini')
  

Limitations and Known Issues

While ConfigConverter is designed to handle a wide range of configuration files, there are some limitations due to inherent differences between configuration formats:

• Format Incompatibilities:

  • INI Format Limitations:

    • No Nested Structures: INI files do not support nested sections or hierarchical data.
    • All Values are Strings: INI treats all values as strings, lacking native support for integers, booleans, or lists.
    • Loss of Hierarchy: Nested data from formats like JSON, YAML, or TOML may be flattened when converted to INI, leading to potential loss of context.

  • XML Format Limitations:

    • Complex Representation: XML can represent nested structures but may not handle data types like booleans or integers without additional schema definitions.
    • Attributes vs. Elements: Differentiating between attributes and elements can complicate the parsing and emitting processes.
