Frequently Asked Questions
What is JSONPath?
JSONPath is a query language for JSON, similar to XPath for XML. It lets you navigate JSON structures and extract specific values using expressions like $.store.book[*].author or $.users[?(@.age > 21)].
What does the $ symbol mean?
The $ symbol represents the root element of the JSON document. All JSONPath expressions start with $. For example, $.name selects the "name" field at the top level of the JSON object.
Can I use filter expressions?
Yes. Filter expressions use the syntax [?(@.field operator value)] to select elements that meet a condition. For example, $.products[?(@.price < 50)] selects all products with a price less than 50.
