JSONPath tester

JSONPath is a query language for picking values out of JSON documents, similar to XPath for XML. It is used in API testing tools, Kubernetes kubectl -o jsonpath, AWS Step Functions, n8n and Postman. This tester runs an expression against your JSON and shows the matching values, so you can get the path right before putting it into code or configuration.

How to use it

1. Paste a JSON document.
2. Type a JSONPath expression.
3. Review the matched values.

Supported syntax

• $: the root.
• .prop or ['prop']: a child property. Use brackets for names with spaces or special characters.
• [0]: an array index.
• [*] or .*: all children.
• ..: recursive descent, searching all levels.

Filter expressions such as [?(@.price < 10)], which some JSONPath implementations offer, are not part of this subset.

Examples

For a document like { 'store': { 'book': [ { 'title': 'Dune', 'author': 'Herbert', 'price': 9 }, { 'title': 'Emma', 'author': 'Austen', 'price': 7 } ], 'bicycle': { 'price': 120 } } }:

• $.store.book[0].title returns Dune.
• $.store.book[*].author returns Herbert and Austen.
• $..price returns 9, 7 and 120, every price at any depth.
• $.store.* returns the book array and the bicycle object.

Tips

• Implementations differ in details. RFC 9535, published in 2024, standardises JSONPath, but older tools may behave slightly differently.
• Recursive descent is convenient but can match more than you expect in large documents; prefer explicit paths in production.
• kubectl uses a JSONPath variant with curly braces, such as {.items[*].metadata.name}.
