About JSONPath Tester

Our JSONPath Tester lets you test and evaluate JSONPath expressions against JSON data in real-time. JSONPath is a query language for JSON, similar to XPath for XML. It allows you to extract specific values from complex JSON structures using path expressions. This tool supports all standard JSONPath features including wildcards (*), recursive descent (..), array indexing, slicing, and filter expressions. Perfect for API debugging, data extraction, and learning JSONPath syntax.

How to Use

  1. Paste your JSON data or click Load Demo to try with sample data
  2. Enter a JSONPath expression in the query field
  3. Results update in real-time as you type
  4. Click common path examples to quickly test different queries
  5. Copy the extracted results for use in your application

Frequently Asked Questions

What is JSONPath?

JSONPath is a query language for JSON data, similar to XPath for XML. It uses path expressions to navigate and extract data from JSON documents. The root element is represented by $ and you can access nested properties using dot notation or bracket notation.

What does the .. operator do?

The recursive descent operator (..) searches for the specified element at any depth in the JSON structure. For example, $..author finds all author properties anywhere in the document, regardless of how deeply nested they are.

How do filter expressions work?

Filter expressions use the syntax [?(@.property condition)] to select array elements that match a condition. For example, $..book[?(@.price<10)] selects all books with a price less than 10. The @ symbol refers to the current element being evaluated.

What is array slicing?

Array slicing uses the syntax [start:end:step] to select a range of elements. For example, [0:2] selects the first two elements, [:2] also selects the first two, and [-1] selects the last element. The step parameter is optional.
