JSON Path Query

JSON Path Query lets you extract data from JSON documents using JSONPath expressions — the XPath-equivalent for JSON defined by Stefan Goessner and widely adopted in Kubernetes admission webhooks, AWS EventBridge rules, jq, and Python's jsonpath-ng library. JSONPath supports child access, wildcard selectors, array slices, filter expressions, and recursive descent operators, enabling precise extraction of specific values from deeply nested real-world API responses without writing code.

How to Use

Paste your JSON document into the upper panel, then enter a JSONPath expression in the query field — start with $ to reference the root. The matching results appear immediately in the results panel with the count of matches found. Use the expression reference panel for quick syntax reminders for child, recursive, wildcard, slice, and filter operators. Multiple matches from wildcard and recursive expressions are displayed as a JSON array for easy inspection.

Common Use Cases

• •API developers prototyping and testing JSONPath expressions for Kubernetes ValidatingWebhookConfiguration admission rules, AWS EventBridge event pattern filters, or Grafana data transformation queries before deploying
• •Backend engineers extracting specific nested values from large, complex API responses like Salesforce results, Google Analytics API payloads, or GraphQL query outputs without writing client-side parsing code
• •Data engineers building ETL pipelines with tools like Apache NiFi, AWS Step Functions, or Azure Logic Apps where JSONPath expressions select specific fields from event records for transformation
• •QA automation engineers writing Postman test assertions using JSONPath expressions to extract and validate specific values from API test responses
• •DevOps engineers debugging Kubernetes kustomize patches, Helm template expressions, or OPA Rego policies that use JSONPath-like syntax to navigate and transform JSON configuration objects
