What Is a JSONPath Evaluator?
A JSONPath evaluator lets you query and extract data from JSON documents using JSONPath expressions. JSONPath is a query language for JSON, similar to XPath for XML. It provides a convenient way to navigate through nested JSON structures, select specific values, and filter arrays without writing custom parsing code.
How to Use This JSONPath Evaluator
- Paste or type your JSON data in the input area.
- Enter a JSONPath expression such as
$.store.book[0].title. - Click "Evaluate" to see matching results.
- Copy the result using the Copy button.
Supported JSONPath Syntax
This tool supports the core JSONPath operators: $ (root), . (child), [] (subscript), [*] (wildcard), and numeric indices like [0] or [1]. These cover the most common querying needs for inspecting API responses, configuration files, and other JSON data.
Frequently Asked Questions
What does the $ symbol mean in JSONPath?
The dollar sign $ represents the root object of the JSON document. All JSONPath expressions start with $ to indicate the beginning of the path traversal.
Can I use JSONPath to select all items in an array?
Yes, use the wildcard operator [*] to select all elements. For example, $.store.book[*].title returns the title of every book in the array.
