How do I test a JSONPath expression online?

Paste your JSON into the left box, then type an expression such as $.store.book[*].author. The matching values and their paths appear as you type.

What does $.. mean in JSONPath?

The $ is the root of the document and .. is recursive descent, so $..price returns every price field at any depth.

How do I filter an array in JSONPath?

Use a filter expression: $.store.book[?(@.price < 10)] keeps the books whose price is under 10. Use @ for the current item, and [?(@.isbn)] to keep items that have a property.

Is my JSON sent to a server?

No. The expression runs in your browser, and filter scripts are limited to a safe subset instead of running arbitrary code.

Valid JSON

JSONPath expression

Uses JSONPath (jsonpath-plus). Paths without a leading $ are treated as starting at the document root. Filter scripts run in a safe subset in the browser.

JSONPath syntax cheat sheet

Syntax	Meaning
`$`	The root of the document
`.key or ['key']`	A child property
`..`	Recursive descent: search at any depth
`*`	Wildcard: every child
`[0]`	An array index
`[0,1]`	A union of indexes or keys
`[-1:]`	A slice (here, the last item)
`[?(@.price < 10)]`	A filter; @ is the current item

An expression without a leading $ is treated as starting at the root. Everything runs in your browser; no JSON is sent to a server.
