Our free JSONPath Selector Tester provides a client-side solution to query, navigate, and extract property values from complex nested JSON objects. Supports standard JSONPath expressions including root notation ($), wildcard property matching (*), array index filtering ([0], [*], [0:2]), and recursive descent deep searches (..price). Designed for API developers, data engineers, and backend automation specialists, it parses raw JSON, calculates match item counts, formats raw payloads, and exports matching nodes to result.json. Operating 100% in local browser JavaScript, your data payload is never uploaded to external servers.
$, *, ..key, [0:2], [*])Matches: X items)result.jsonPaste your raw JSON document into the input editor, click a sample preset button, or upload a local .json file.
Enter your JSONPath expression (e.g., $.store.book[*].title or ..price) into the query input bar.
Inspect the live evaluated JSON nodes, check the match count badge, and download result.json.
Supports root navigation, wildcard key extraction, array slicing, and recursive property searches throughout deep JSON trees.
Prettify unindented payloads or minify raw input JSON before executing path query evaluations.
All JSON parsing, path query evaluation, and file downloads execute locally in your browser. Sensitive API payloads are never sent to external servers.
JSONPath is a declarative query language designed to navigate and extract specific nodes from deeply nested JSON documents, analogous to XPath for XML documents.
Expressions begin with the root selector ($). Key operators include dot notation ($.store.book), recursive descent (..price), wildcards ([*]), and array slicing ([0:2]).
Testing JSONPath expressions client-side simplifies REST API debugging, automated test suite verification, and microservice payload transformation pipelines without sending sensitive JSON payloads over the network.
