JSONPath
JSONPath Tester
Query JSON data locally with a safe JSONPath subset.
Input
Provide JSON and a JSONPath expression.
All processing happens locally in your browser. No input is sent to a server.
Limits: JSON 500KB, path 1024 bytes, node visits 50000, results 1000
Results
0 results · 0 node visits
Run a query to see matched results.
What

How To
How to test JSONPath
Paste JSON and evaluate a path expression.
1
Paste JSON
Paste your JSON payload in the input panel.
2
Enter JSONPath
Type a JSONPath expression such as $.store.book[*].author.
3
Run query
Run the query and copy matched path/value pairs.
Knowledge
Understanding JSONPath
What is JSONPath?
JSONPath is a path language to navigate and query JSON data structures.
Root and properties
$ represents the root. Use .name or ['name'] to access object properties.
Array access
Use [index] for a specific element or [*] for all elements in an array.
Recursive descent
..name recursively finds matching properties across descendants.
Security model
Excluding script evaluation keeps querying deterministic and safer in-browser.
FAQ
JSONPath Tester FAQ
Which syntax is supported?
$ , .name, ['name'], [index], [*], ..name, ..* are supported.
Do you support filters like [?()]?
No. Filter/script expressions are intentionally excluded for security.
Is my JSON uploaded?
No. Parsing and evaluation run only in the browser.
What happens when results are huge?
Traversal/result limits stop execution safely.
Is there a path-length limit?
Yes. Path input is limited to 1KB.
What if I use unsupported syntax?
You will get a clear parse error message.
How do wildcards work?
[*] and .* iterate over all direct children of the current node.
Is recursive search expensive?
Yes. On large JSON trees, recursive queries can quickly hit visit limits.
