JSONPath Query Tester: Extract Data Instantly
Use JSONPath to query and extract specific values from any JSON document — just like XPath for XML. Paste your JSON on the left, type a JSONPath expression, and see matching results immediately.
- Dot notation:
$.store.book[0].title - Wildcard:
$.users[*].email - Recursive descent:
$..price— finds allpricekeys at any depth. - Filter expressions:
$.books[?(@.price < 10)] - Privacy-First: All evaluation happens in your browser — nothing is uploaded.
JSONPath Syntax Reference
| Expression | Meaning |
|---|---|
| $ | Root element |
| $.key | Child named key |
| $[0] | First array element |
| $[*] | All array elements |
| $..key | Recursive search for key |
| $.a.b | Nested dot notation |
| $[?(@.x > 5)] | Filter: items where x > 5 |
| $.a[1:3] | Array slice (index 1 to 2) |
JSONPath in Practice
Sample JSON
{
"store": {
"books": [
{ "title": "Refactoring",
"price": 45 },
{ "title": "Clean Code",
"price": 30 }
]
}
}Common Use Cases
API Response Exploration
Quickly extract field subsets from large API payloads without writing code.
Log Analysis
Use recursive descent ($..error) to find error fields anywhere in structured log entries.
Config Inspection
Filter arrays with [?(…)] to extract only the config entries matching your criteria.
Frequently Asked Questions
Is my data safe with this JSON tool?
Yes. This tool uses 100% client-side processing. Your JSON data never leaves your browser and is never sent to our servers, ensuring maximum privacy and security.
What is JSONPath?
JSONPath is a query language for JSON, similar to XPath for XML. It lets you navigate and extract values from JSON documents using path expressions like $.users[*].name or $..price.
What does the recursive descent operator (..) do?
The .. operator searches all levels of the JSON tree regardless of depth. For example, $..price finds every "price" key anywhere in the document — no matter how deeply nested.
How do filter expressions work?
Filter expressions use the syntax [?(@.field operator value)]. The @ symbol refers to the current element. For example, $.books[?(@.price < 30)] returns books with a price below 30.
