YAML ⇄ JSON Converter
Convert between YAML and JSON formats instantly.
YAML and JSON both represent the same kinds of structured data but with very different syntax - YAML favors readable indentation, JSON favors explicit brackets and braces. This tool converts between them in either direction, useful when a tool or config system expects one format but you have data in the other.
Frequently asked questions
For standard data structures, yes - both formats represent the same underlying data (objects, arrays, strings, numbers), so a round trip generally preserves the content, though YAML-specific features like comments won't survive since JSON has no concept of comments.
Basic anchors/aliases (YAML's way of reusing a block of data) are typically resolved into their expanded form when converting to JSON, since JSON has no equivalent shorthand.
That depends on what your specific tool/platform expects - many modern DevOps tools (Kubernetes, Docker Compose, CI/CD pipelines) prefer YAML for its readability, while JSON is the near-universal standard for APIs.
