도구 소개
Paste YAML and get structured JSON back. Handy for debugging CI configs, feeding YAML into a tool that only speaks JSON, or just inspecting what your config actually resolves to.
도구 개요
The converter tokenizes your YAML line by line, tracks indentation to build the hierarchy, and resolves scalars to their JSON-native types (numbers, booleans, null, strings). Both block style (indented) and flow style ([a, b] / {k: v}) mappings and sequences are supported, along with comments, single- and double-quoted strings, and the usual `null`/`~`/`true`/`false` aliases.
사용 사례
- Inspect a Kubernetes manifest as JSON
- Pipe a YAML config into jq or a JSON Schema validator
- Convert Docker Compose files for tools that require JSON
- Debug why a CI config is being parsed a certain way

}자주 묻는 질문
Is this YAML to JSON converter free?+
Yes. It runs entirely in your browser, with no sign-up, no file-size gates, and no ads inside the tool.
What subset of YAML is supported?+
Block and flow mappings/sequences, plain and quoted scalars, comments, and null/boolean/number resolution. Anchors (&), aliases (*), tags (!!type), and multi-line scalars (|, >) are not yet supported.
Will it coerce numeric strings like "007"?+
Leading-zero strings are kept as strings. Only values that match a strict integer or float pattern are converted to numbers.
Is my data sent to a server?+
No. Parsing and conversion happen entirely in your browser — the page never talks to a backend.
Can I convert Kubernetes, Docker Compose, or GitHub Actions YAML?+
Yes. Those configs use the block/flow features this converter supports. Paste the file and the resulting JSON is ready for jq, JSON Schema validators, or direct import into code.
