How to Query and Filter JSON Arrays with JSONPath

Our free online JSONPath finder is an essential utility for developers working with large, complex data structures and arrays. JSONPath is a standardized query language that allows you to target specific nodes in a JSON document, much like XPath for XML. Whether you need to extract all user IDs from an API response, find specific values deep within nested arrays, or filter objects based on property values, our tool provides real-time, client-side extraction with zero data latency and absolute privacy.

Array Query Examples

Get all items in an array:$[*] or $.items[*]
Filter by property value:$[?(@.status == 'active')]
Extract specific field from array:$.users[*].email
Get first 3 items:$.data[0:3]

Advanced Filters

Recursive Descent (..): Search for a key anywhere in the document (e.g., $..id).
Wildcards (*): Match any property name or array index.
Script Expressions: Use ?() to apply logical conditions (and, or, not).
Slicing: Extract ranges from arrays using [start:end:step] syntax.
Multi-select: Pick multiple specific keys using $..['id','name'].

Frequently Asked Questions

What is the default JSONPath expression?

The default expression is $, which represents the root of the JSON document and returns the entire input. To start filtering, you can use dot notation (e.g., $.users) or bracket notation (e.g., $['users']).

How do I extract a specific field from an array of objects?

If you have an array of users and want only their names, use the wildcard operator: $.users[*].name. This will return a new array containing only the values of the 'name' property for every object in the list.

Can I filter by specific criteria?

Yes, JSONPath supports filter expressions using ?(). For example, $.store.book[?(@.price < 10)] will return all books with a price less than 10.
