JSON to YAML Converter
Convert JSON to YAML.
How JSON to YAML conversion works
Step 1
Paste your JSON
Add a JSON object or array into the input box.
Step 2
Convert
The tool parses the JSON and rewrites it as indented YAML, preserving nested objects and arrays.
Step 3
Copy the result
Copy the YAML output for use in configuration files such as Docker Compose, CI pipelines or Kubernetes manifests.
Frequently asked questions
Does the input need to be valid JSON?
Yes. If the JSON can't be parsed, the tool shows an "Invalid JSON" message instead of a result.
Are nested objects and arrays supported?
Yes. Nested structures are converted recursively, with each level indented under its parent key.
Is my data uploaded anywhere?
No. The conversion runs locally in your browser.
