YAML/JSON Path Tester - JSONPath & YAML Path Expression Tester

What is JSONPath?

JSONPath is a query language for JSON, similar to XPath for XML. It provides a way to extract specific data from a JSON document using path expressions. JSONPath is widely used in DevOps tools, CI/CD pipelines, and API testing.

Common JSONPath Operators

Common Use Cases

Kubernetes Configuration

JSONPath is built into kubectl for extracting data from resources:

# Get all pod names
kubectl get pods -o jsonpath='{.items[*].metadata.name}'

# Get container images from a deployment
kubectl get deployment nginx -o jsonpath='{.spec.template.spec.containers[*].image}'

# Get all node IP addresses
kubectl get nodes -o jsonpath='{.items[*].status.addresses[?(@.type=="InternalIP")].address}'

CI/CD Pipelines

Extract values from configuration files:

# GitHub Actions example
- name: Get version
  run: |
    VERSION=$(cat package.json | jq -r '.version')
    echo "VERSION=$VERSION" >> $GITHUB_ENV

API Response Parsing

Query API responses in tests or scripts:

// Using JSONPath to extract data
const authors = jsonpath.query(response, '$.store.book[*].author');
const cheapBooks = jsonpath.query(response, '$.store.book[?(@.price < 10)]');

YAML Path Expressions

YAML path expressions work similarly to JSONPath but are designed for YAML documents. Since YAML is a superset of JSON, you can use the same path syntax:

# Kubernetes Pod manifest
apiVersion: v1
kind: Pod
metadata:
  name: my-pod
  labels:
    app: nginx
spec:
  containers:
  - name: nginx
    image: nginx:1.14.2

Path expressions for this YAML:

• metadata.name → my-pod
• metadata.labels.app → nginx
• spec.containers[*].image → ["nginx:1.14.2"]

Filter Expressions

Filter expressions allow you to select elements based on conditions:

Privacy & Security

All processing happens directly in your browser:

• No Server Communication: Your JSON/YAML data never leaves your device
• No Storage: Nothing is saved to localStorage, cookies, or servers
• Open Source: All code is transparent and auditable
