🔍 What is JSONPath Tester?
JSONPath is a path expression language for extracting specific values from JSON data. Just like XPath selects nodes in XML documents, JSONPath navigates through JSON data structures. It is widely used for API response analysis, data extraction automation, and configuration validation. This tool lets you write path expressions and instantly see the results.

Frequently Asked Questions
What is the difference between JSONPath and JSON Pointer?▼
JSONPath is a query language supporting wildcards and filters, while JSON Pointer (RFC 6901) only allows simple path specification. JSONPath is more flexible, but JSON Pointer is standardized.
Is all JSONPath syntax supported?▼
This tool supports basic syntax (property access, array index, wildcards). Filter expressions (?()) and slices ([start:end]) are partially supported.
What happens when JSONPath returns multiple results?▼
When using wildcards (*), multiple values are returned as an array. For example, $.books[*].title returns all book titles as an array.
