Why convert JSON to YAML?
- Human-readable config. YAML's indented layout is easier to read and edit by hand than JSON.
- Config-tool native. YAML is the default for Docker Compose, Kubernetes, CI pipelines, and Ansible.
- Lossless structure. Objects and arrays map directly to YAML keys and lists.
How it works
- Use the converter. Go to the Formatly JSON to YAML converter page. No registration is required.
- Upload your JSON file. Drag and drop your JSON document into the uploader, or browse from your device.
- Convert to YAML. Select YAML as the target format and click the Convert button.
- Download the YAML file. Click the Download button to save the converted YAML document.
Good for
- Converting a JSON config into a readable YAML file.
- Preparing data for Kubernetes, CI, or Ansible.
- Hand-editing structured data more comfortably.
FAQ
How does the converter handle hierarchical nesting? The engine maps your JSON's nesting into indented, block-style YAML — objects become nested keys and arrays become dash lists. Note that keys are emitted in alphabetical order, not their original JSON order, so a config that relies on key ordering may need a quick reorder afterwards.
Can I convert YAML back to JSON? Yes, we support bidirectional data conversion. You can convert your configurations in either direction easily using the target format menu.
Is my configuration kept private? Absolutely. Formatly operates on secure cloud servers. All files are automatically deleted after exactly 1 hour. No signups or data tracking are active.
