JSON ↔ YAML Converter
Convert JSON to YAML and YAML to JSON with live preview and one-click copy for Kubernetes, CI, and API configs.
About this tool
Move configuration between JSON-first APIs and YAML-first tools such as Kubernetes manifests, GitLab CI, and Ansible playbooks. Paste either format, switch direction, and copy the converted document without reformatting by hand.
What you get
- JSON → YAML with nested maps, lists, and scalar values
- YAML → pretty-printed JSON with 2-space indent
- Bidirectional mode switch without losing input
- Parse errors with a clear message and line context

FAQ
How do I convert JSON to YAML online?
Paste valid JSON, choose JSON→YAML, and copy the output. Nested objects become indented maps and arrays become YAML lists.
Can I convert YAML back to JSON?
Yes—switch to YAML→JSON and paste your YAML document. The result is pretty-printed JSON you can drop into APIs or config tools.
Is JSON to YAML conversion lossless?
For standard nested objects, arrays, strings, numbers, booleans, and null, the structure is preserved. Comments and YAML-specific anchors are not carried into JSON.
Why convert between JSON and YAML?
APIs and front-end tooling often use JSON, while Kubernetes, CI pipelines, and Ansible favor YAML. Converting saves manual reformatting when moving configs between stacks.
Can I convert Kubernetes YAML to JSON online?
Yes—paste manifest YAML, switch to YAML→JSON, and copy pretty-printed JSON for APIs, scripts, or validation tools.
