frequently asked questions
Is voiddo yaml a good json2yaml.com alternative?
Yes. voiddo yaml auto-detects whether you paste YAML or JSON and converts in both directions — something json2yaml.com (JSON → YAML only) and yaml2json.com (YAML → JSON only) split across two tools. If you regularly need to convert in both directions, voiddo yaml is simpler because you paste and it figures out what to do.
Can I convert a Kubernetes or Docker Compose YAML file?
Yes. Paste the YAML content into the input. The tool auto-detects it as YAML and converts to JSON. Kubernetes manifests, Docker Compose files, GitHub Actions workflows, and Helm values files all use standard YAML 1.2 syntax supported by this converter. Note: comments will be stripped in the JSON output because JSON does not support comments.
Why does my YAML convert to a different structure than expected?
YAML allows multiple representations for the same data. For example, 'true', 'yes', 'on' are all boolean true in YAML 1.1 (but only 'true'/'false' in YAML 1.2). This tool uses js-yaml in YAML 1.2 mode. Bare numbers without quotes become JSON numbers. If you see unexpected type coercion, quote the value in your YAML (e.g. "123" stays a string).
Does this tool support YAML anchors and aliases?
Yes. YAML anchors (&anchor) and aliases (*anchor) are resolved during parsing. In the JSON output they are inlined — the alias is replaced by the full value of the anchor. The round-tripped YAML (JSON → YAML) will not reconstruct the anchors, but the data is identical.
Is this YAML converter free?
Yes, completely free with no account, no ads, and no rate limits. It is part of the 49 free tools available at tools.voiddo.com.
