About
The JSON ⇄ YAML Converter transforms JSON data to YAML format and back, making it easy to work with configuration files for Kubernetes, Docker Compose, GitHub Actions, and other tools that prefer YAML. The converter preserves data types, arrays, and nested objects faithfully in both directions.
How to use
- 1 Paste your JSON in the left panel to convert it to YAML on the right.
- 2 Switch direction to paste YAML and get JSON back.
- 3 Copy the result or compare both representations side by side.
- Why would I convert JSON to YAML?
- YAML is far easier to read and write for configuration files because it uses indentation instead of braces and brackets, supports comments (which JSON does not), and requires less punctuation. Tools like Kubernetes, Helm, Docker Compose, Ansible, and GitHub Actions all use YAML for their configuration files.
- Are there any data types that do not convert cleanly between JSON and YAML?
- JSON and YAML share the same core data model (strings, numbers, booleans, null, arrays, objects), so standard data converts cleanly in both directions. YAML-specific features like anchors, aliases, and multi-line strings have no JSON equivalent and are simplified during YAML → JSON conversion.
- Does the converter preserve the order of keys?
- Yes. The converter preserves the original key order when converting in both directions. This matters for diff readability in version-controlled configuration files where a change in key order would produce a noisy, misleading diff.
