YAML Path Evaluator
Query YAML documents with dot-notation or bracket-notation paths. Enter YAML content and a path expression to extract specific values. Supports nested objects, arrays, and mixed structures. Built-in YAML parser handles common configurations. Runs entirely in your browser — your data never leaves your machine.

All interactive tools run entirely in your browser. Your data never leaves your device.
How It Works
Enter YAML content in the top textarea and a path expression in the input field. Use dot notation (server.host) to access nested keys and bracket notation (users[0].name) to access array elements. The tool parses the YAML, traverses the path, and displays the result with its type.
Features
- Dot notation: access nested values with
key.subkey.deepkey - Bracket notation: access array elements with
items[0]or keys withdata["key"] - Type detection: shows the result type (string, number, boolean, object, array, null)
- Built-in YAML parser: handles maps, sequences, scalars, inline arrays, comments
- Copy result: one-click copy of the extracted value
- 5 preset examples: Nested Object, Array Index, Docker Compose, K8s Deployment, CI/CD Pipeline
- Private: all parsing runs in your browser — no data transmitted
Use Cases
- Quickly extracting values from Kubernetes manifests and Helm charts
- Debugging Docker Compose and CI/CD pipeline configurations
- Exploring unfamiliar YAML configs without opening the full file
- Validating that a specific YAML path resolves to the expected value
- Teaching YAML structure and path navigation
