JSON to YAML Converter

Convert JSON documents into clean, human-readable YAML in one paste. This JSON to YAML converter preserves nesting, arrays and data types while stripping the braces and quotes that make JSON noisy for configuration files. It's ideal for turning API responses or generated JSON into the format Kubernetes, GitHub Actions and Ansible actually expect.

• Preserves objects, arrays, numbers, booleans and null with correct YAML types
• Configurable indentation (2 or 4 spaces) to match your project's style
• Quotes strings only when required, keeping output minimal and readable
• Handles deeply nested structures without flattening or data loss
• Emits block-style sequences and mappings that diff cleanly in Git
• Instant conversion as you type - no upload, no build step, no wait

1. 1

   Paste your JSON

   Drop a JSON object or array into the input panel. Malformed JSON is flagged before conversion so you can fix it first.

2. 2

   Convert to YAML

   The tool parses your JSON and re-serializes it as YAML instantly, mapping each type to its YAML equivalent.

3. 3

   Copy or download

   Copy the YAML to your clipboard or download it as a .yaml file, ready to drop into a config or manifest.

• Convert an API JSON response into a YAML fixture for tests
• Author Kubernetes manifests or Helm values from generated JSON
• Migrate a package.json-style config into a YAML equivalent
• Produce readable YAML for GitHub Actions or GitLab CI pipelines
• Turn a JSON settings blob into a commentable YAML config file
