JSON to YAML Converter
Paste JSON and get clean YAML configuration output instantly.
About the JSON to YAML Converter
This tool converts JSON to YAML with correct two-space indentation and quoting. Nested objects become indented blocks and arrays become dash lists, which is the form Kubernetes manifests, Docker Compose files, GitHub Actions workflows and CI pipelines all expect.
Convert JSON to YAML because the tooling world is split down the middle. APIs speak JSON; Kubernetes, Docker Compose, GitHub Actions, GitLab CI and Ansible all want YAML. Retyping a manifest by hand is where a stray space breaks a deployment.
The conversion handles the parts people get wrong: two-space indentation applied consistently, arrays written as dash lists, and quoting added only where YAML needs it. Strings such as yes, no, on, off and version numbers like 1.10 are quoted so YAML does not silently read them as booleans or numbers.
Nested structures of any depth are supported, and the output is valid YAML you can drop straight into a repository.
How to use the JSON to YAML Converter
- Paste your JSON. Provide the JSON object or array you want converted.
- Convert. Run the conversion to produce indented YAML.
- Check the quoting. Look over values such as yes, no and version numbers, which are quoted deliberately.
- Copy or download. Copy the YAML or save it as a .yaml file.

Frequently asked questions
Why does the YAML quote some values?
Because YAML would otherwise misread them. Strings like yes, no, on, off and 1.10 are quoted so they stay strings.
What indentation is used?
Two spaces per level, applied consistently, which is the convention Kubernetes and CI tools expect.
How are arrays converted?
As dash lists, with one item per line, nested to the correct depth.
Is there a nesting depth limit?
No. Objects and arrays nested to any depth are converted.
Can I convert YAML back to JSON?
Yes. Use the YAML to JSON converter for the reverse direction.
