Overview
JSON to YAML Converter — Online & Free
Convert JSON to YAML for Kubernetes manifests, Docker Compose files, CI workflows, Ansible vars, and human-edited configuration. YAML's indentation-based syntax and support for comments make nested settings easier to read than raw JSON. JsonDrift transforms valid JSON into clean YAML instantly — in your browser, with no account and no data upload.
JSON vs YAML: when to convert
JSON is ideal for APIs, logs, and machine-generated data — strict syntax, universal parsers, no ambiguity. YAML is ideal when humans edit configs: fewer quotes, natural multiline strings, and comments for documentation inline.
Many platforms accept both. Kubernetes and GitHub Actions use YAML; most REST APIs use JSON. This converter helps you move between ecosystems without manual retyping.
What the converter produces
Objects map to YAML mappings with indented keys. Arrays become YAML sequences with dash items. Nested structures preserve hierarchy through indentation. Scalar strings, numbers, booleans, and null convert to YAML scalars with quoting when needed.
Common workflows
- Turn API JSON samples into example YAML configs for docs
- Convert generated JSON settings to YAML for Helm or Kustomize
- Migrate JSON config stores to YAML-based deployment tools
- Preview how structured data will look in YAML-driven pipelines
Round-trip caveats
YAML supports anchors, aliases, and comments that JSON does not. Converting JSON → YAML → JSON may not reproduce comments or YAML-specific features. Always validate in your target runtime (kubectl apply, CI parser, etc.).
FAQ
Frequently asked questions
Is YAML reversible to JSON?
Often yes for data-only YAML. Comments and YAML anchors may not round-trip perfectly.
Can I convert invalid JSON?
No. Input must be valid JSON before YAML conversion.
Is this suitable for Kubernetes?
Yes for structural conversion. Always run kubectl apply --dry-run or your linter before production.
Does conversion upload my config?
No. Everything runs locally in your browser.
