A powerful CLI tool for bidirectional conversion between JSON, YAML, TOML, and ENV config formats with smart type inference, validation, flatten/unflatten operations, schema generation, and automatic shell completion support.

Features

Bidirectional Conversion: Convert between any combination of supported formats
Smart Type Inference: Automatically detect and convert string values to appropriate Python types
Syntax Validation: Validate syntax of input files before conversion
Flatten/Unflatten: Transform nested structures to/from dot-notation keys
Schema Generation: Generate JSON Schema from parsed configurations
Shell Completion: Built-in support for bash, zsh, and fish completions
Offline Operation: Runs entirely offline with minimal dependencies
Rich Output: Beautiful terminal output using Rich library

Installation

From PyPI

pip install config-convert-cli

From Source

git clone https://7000pct.gitea.bloupla.net/7000pctAUTO/config-convert-cli.git
cd config-convert-cli
pip install -e ".[dev]"

Quick Start

Convert between formats

# Convert JSON to YAML
config-convert convert input.json --to yaml -o output.yaml

# Convert YAML to JSON with custom indentation
config-convert convert config.yaml --from yaml --to json --indent 4

# Convert ENV to JSON
config-convert convert .env --from env --to json

# Read from stdin
cat config.json | config-convert convert --stdin --from json --to yaml

# Pretty print output
config-convert convert config.json --to yaml --indent 2

Validate syntax

# Validate a config file
config-convert validate config.yaml

# Validate from stdin
echo '{"name": "test"}' | config-convert validate --stdin --format json

Flatten nested structures

# Flatten nested JSON to ENV format
config-convert flatten config.json --output flat.env

# Flatten to another structured format
config-convert flatten config.json --format yaml

Unflatten to nested structures

# Unflatten ENV to JSON
config-convert unflatten flat.env --format json --output nested.json

Generate JSON Schema

# Generate schema from config
config-convert schema config.json -o schema.json

# Generate and display schema
config-convert schema config.json
