What Is JSONPath?
JSONPath is a query language for JSON, similar to XPath for XML. It allows you to navigate and extract data from JSON structures using path expressions. For example, $.store.book[0].title accesses the title of the first book in a store.
JSONPath is essential for:
- Data Extraction: Querying specific values from complex JSON.
- API Testing: Verifying specific fields in API responses.
- Data Transformation: Selecting fields for mapping or ETL.
- Debugging: Quickly locating values in large JSON structures.
How to Use the JSONPath Tester
- Paste JSON data: Enter your JSON structure in the input box.
- Add a JSONPath: On a new line, enter a path expression starting with
$. - Click Evaluate: View the extracted value(s) in the output.
Frequently Asked Questions
What JSONPath syntax is supported?
The tool supports dot notation ($.store.book), bracket notation ($['store']['book']), array indexing ($[0]), wildcards ($.*), and deep scan.
How do I separate JSON from the path?
Paste the JSON first. Add the JSONPath expression on a new line. Lines starting with $ or . are treated as the path.
