JSONPath is an expression language for JSON documents (similar to XPath for XML) designed to easily extract, filter, and traverse structured values from nested data payloads.

What does the "$" symbol represent in JSONPath?

The "$" symbol denotes the root object or array in the JSON document from which all queries begin.

How do I perform a recursive deep search for a property?

Use the double dot operator "..", for example $..price finds all properties named "price" anywhere inside the document hierarchy.

Can I extract all items in an array?

Yes. Use the wildcard asterisk syntax like $.items[*] or $.users[*].name to extract all values across list entries.

Is my JSON query processed privately?

Yes. All JSON parsing and JSONPath evaluations are performed purely within your browser runtime. No data is sent over the network.
