About Convert YAML to JSON
Config files, CI/CD workflows, and Kubernetes manifests are often written in YAML, but plenty of code and tooling expects JSON instead — converting between them by hand risks subtle mistakes since YAML's syntax (indentation-based nesting, unquoted strings, block scalars) doesn't map onto JSON in an obvious character-by-character way. This tool does a genuine parse-and-reserialize conversion using `js-yaml`, the same library many JavaScript tools rely on.
Because it's a real parser rather than a text-substitution trick, it correctly handles YAML's full feature set: nested mappings become nested JSON objects, sequences become JSON arrays, and YAML's flexible scalar types (quoted, unquoted, multi-line) all resolve to their correct JSON equivalents.
This is useful for feeding a YAML config into a JSON-only system, debugging what a YAML file actually parses to (useful when YAML's implicit typing surprises you — like `yes` becoming boolean `true`), or converting a Docker Compose or CI workflow file into JSON for programmatic processing.
How it works
- Paste your YAML. Any standard YAML document.
- Parsing runs automatically. A real YAML parser handles the conversion.
- Copy the JSON output. Correctly nested objects and arrays.
