JSON to YAML Converter
Convert JSON to YAML (or YAML back to JSON) instantly — flip direction with one click.
Why Convert JSON to YAML?
JSON is the preferred format for APIs and data exchange, but YAML is the go-to format for configuration files. Docker Compose, Kubernetes manifests, GitHub Actions workflows, Ansible playbooks, and many CI/CD tools all use YAML because it's far more readable — no curly braces, no quotes for simple strings, and natural nesting through indentation.
This tool converts in both directions. Need to pull a value from a Kubernetes YAML into a JSON API payload? Flip the direction and convert back in seconds.
How to Use
- Paste your JSON (or YAML) into the left input panel.
- Select your conversion direction using the ⇄ Flip Direction button.
- Click Convert to YAML (or Convert to JSON).
- Copy the output or download it as a file.
Frequently Asked Questions
What is the difference between JSON and YAML?
+
JSON uses strict delimiter syntax with braces {} and brackets [] for structure, making it ideal for machine-to-machine data interchange. YAML uses indentation and whitespace, making it more concise and easier for humans to read and edit in configuration files (such as Docker, Kubernetes, and CI/CD pipelines).
Can I convert YAML back to JSON too?
+
Yes. You can click the "⇄ Flip Direction" button in the toolbar to switch the tool to YAML-to-JSON mode. This allows you to paste YAML configuration snippets and instantly convert them into valid, formatted JSON.
Does this tool preserve comments when converting?
+
Because standard JSON specifications do not support comments, converting YAML containing comments into JSON will strip those comments during parsing. When converting from JSON to YAML, the output is generated cleanly from the parsed data structures.
