About JSON-YAML Converter
JSON (JavaScript Object Notation) and YAML (YAML Ain't Markup Language) are two popular data serialization formats used in configuration files, data exchange, and API development.
This converter allows you to easily convert between JSON and YAML formats. YAML is more human-readable with its indentation-based syntax, while JSON is more compact and widely supported in programming languages.
Key Features
Bidirectional conversion: JSON to YAML and YAML to JSON
Custom indentation support (2 spaces, 4 spaces, or tabs)
YAML flow style and block style support
Syntax validation and error reporting
Preserve data types (strings, numbers, booleans, null)
