Instantly convert Kubernetes manifests, Docker Compose files, and CI/CD pipelines between YAML and JSON format. Validates syntax locally and catches line formatting mistakes.
Runs entirely in your browser
YAML and JSON represent the same kind of structured data in different styles — YAML is friendlier to write and read, JSON is what many tools and APIs expect. This converter translates between the two in both directions, so you can move configuration between formats without rewriting it by hand.
It is aimed squarely at the config files developers deal with: Kubernetes manifests, Docker Compose files and CI/CD pipelines, where YAML’s indentation is easy to get subtly wrong. The tool validates the syntax locally and catches the formatting mistakes — a misplaced indent, a bad line — that would otherwise fail only when the tool consuming the file rejects it.
It runs in your browser, so your configuration is not uploaded. Use it to convert a manifest to JSON for a tool that needs it, to sanity-check YAML indentation, or to move config between systems that prefer different formats.
