Common questions about YAML to JSON conversion
Many APIs, tools, and programming languages only accept JSON. Converting YAML config files to JSON lets you use them in REST APIs, JavaScript applications, and tools that don't support YAML natively.
All data values are preserved exactly. However, YAML features without JSON equivalents — comments, anchors, aliases, and multi-line string formatting — are resolved during conversion. Comments are lost since JSON doesn't support them.
YAML types map to JSON types: strings, numbers, booleans, null, arrays, and objects convert directly. YAML dates become strings in JSON. Anchors and aliases are resolved to their actual values during conversion.
Yes. Kubernetes manifests, Helm charts, and Docker Compose files convert cleanly to JSON. Multi-document YAML (separated by ---) is handled as separate JSON outputs. This is useful for kubectl apply with JSON input.
Yes, all conversion happens in your browser. Your YAML data — including any secrets, passwords, or API keys in config files — never leaves your machine.
