Test JSONPath expressions against your JSON data in real-time. JSONPath is a query language for JSON, similar to XPath for XML. This tool supports dot notation, bracket notation, wildcards, recursive descent, array slicing, and filter expressions. Everything runs in your browser — no data is sent to any server.
JSONPath is a query language for extracting specific values from JSON data — like XPath for XML. When working with complex, deeply nested API responses, JSONPath lets you pinpoint exactly the data you need without parsing the entire structure. Common expressions: $.name (root-level name), $.users[0] (first user), $.users[*].email (all user emails), $.store.book[?(@.price < 10)] (books under $10). This tester lets you experiment with expressions against real data, seeing results instantly. Essential for configuring API integrations, building data pipelines, setting up monitoring alerts, and learning the JSONPath syntax.
$ = root, . = child, [] = array index or filter, * = wildcard, .. = recursive descent. Examples: $.users[0].name (first user's name), $..email (all emails at any depth), $.items[?(@.active==true)] (active items).
JSONPath is a query language with implementations in many languages. jq is a command-line JSON processor with its own syntax and transformation capabilities. JSONPath is simpler for basic queries; jq is more powerful for transformations.
Yes — libraries exist for most languages: jsonpath-ng (Python), Jayway JSONPath (Java), jsonpath-plus (JavaScript), and built-in support in many API platforms and tools.
This is a filter expression. ? starts a filter, @ refers to the current element, and the condition follows. It selects all elements where the price property is less than 10.
Standard JSONPath is read-only — it selects data but doesn't modify it. Some implementations add set/delete operations, but that's non-standard. Use your programming language's JSON manipulation for modifications.
