How to Use:

  • Paste your YAML into the Input Text area or click Choose File to load a .yaml, .yml, or compatible text file.
  • Toggle Show data types to display whether each value is an object, array, string, number, etc.
  • Toggle Maximize output to expand the output panel for easier reading.
  • Click Visualize to display the structural outline of your YAML.
  • Use Copy Output to copy the visual structure to your clipboard.

What Visualize YAML Structure can do:

This tool breaks down your YAML into a simplified visual tree that reveals how your data is organized. It shows which keys exist at each level and how deeply nested structures are arranged. You can optionally include the data types so if you’re working with arrays, booleans, or null values, it’s immediately visible. The formatting is clean, indented, and instantly updates as you type or import files. It’s ideal for debugging, exploring unfamiliar files, or documenting config layouts. With live output, a line counter, and export support, this gives you a full snapshot of your YAML structure at a glance.

Example:

Input YAML:
user:
  name: Alice
  skills:
    - Python
    - YAML

Output:
user (object)
  name (string)
  skills (array)
    - (string)
    - (string)

Common Use Cases:

Perfect for developers and engineers reviewing large YAML configs, Kubernetes manifests, or API files. Great for visually checking nested structures, onboarding into complex files, or converting human-readable hierarchy into shareable documentation.

Useful Tools & Suggestions:

Before visualizing the structure, you might want to Prettify YAML so indentation and nesting are crystal clear. And if you need to dig deeper afterward, Show YAML Statistics gives you a breakdown of keys, depth, and value types in one go.
