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.
