JSONPath Syntax Reference

$ Root element
@ Current element (in filters)
. or [] Child operator
* Wildcard (all elements)
[start:end] Array slice
[?(<expr>)] Filter expression

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
#

OperatorDescriptionExample
$Root element$
@Current element (in filters)@.price
.Child operator$.store.book
[]Subscript operator$.store.book[0]
*Wildcard (all elements)$.store.book[*]
[start:end]Array slice$.store.book[0:2]
[?()]Filter expression$.store.book[?(@.price < 10)]

Common Use Cases
#

Kubernetes Configuration
#

JSONPath is built into kubectl for extracting data from resources:

1
2
3
4
5
6
7
8

# 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:

1
2
3

// 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:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11

# 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:

ExpressionDescription
[?(@.price < 10)]Elements where price is less than 10
[?(@.price > 20)]Elements where price is greater than 20
[?(@.category == 'fiction')]Elements where category equals ‘fiction’
[?(@.price != 8.95)]Elements where price is not 8.95

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
