YAML to JSON Converter

YAML to JSON Converter handles bidirectional conversion between YAML and JSON without sending your data to any server. Paste YAML in the left panel and get formatted JSON on the right, or flip to JSON→YAML mode with a single click. The YAML parser is implemented in pure JavaScript and supports the most common YAML features: scalars, sequences, mappings, multi-line strings (literal and folded block styles), nested structures, boolean and numeric type inference, and null values. The JSON to YAML direction produces clean, human-readable output. This is particularly useful for Kubernetes configs, Docker Compose files, CI/CD pipelines, and any workflow where YAML and JSON need to interoperate.
