Why Use JSON Converter?

JSON (JavaScript Object Notation) is the most popular data interchange format, but different systems often require different configuration formats:

YAML - Perfect for configuration files, more readable than JSON
TOML - Great for application configuration, unambiguous syntax
TOON - Advanced format with unique features for complex configurations

Common Use Cases:

• Converting API responses to configuration files
• Migrating from JSON to YAML for Docker Compose
• Converting JSON configs to TOML for Rust applications
• Validating JSON syntax before deployment
• Formatting minified JSON for readability
