YAML to JSON Converter

YAML to JSON Converter provides bidirectional conversion between YAML and JSON formats using the industry-standard js-yaml library. The YAML to JSON tab accepts any valid YAML document and converts it to formatted JSON with syntax highlighting. The JSON to YAML tab accepts JSON and produces clean YAML. Both directions validate their input and display inline errors with line numbers so you know exactly where a syntax problem is. YAML configuration files are common in DevOps workflows: Kubernetes manifests, Docker Compose files, GitHub Actions workflows, and Ansible playbooks are all YAML. The JSON to YAML direction offers three options: indent size, line width, and quote style.
