JSONPath Query Tester

What is JSONPath Query Tester?

JSONPath is to JSON what XPath is to XML: a single path expression extracts data from nested structures — $.store.book[*].author pulls out every author. When facing an API response hundreds of lines long, JSONPath locates the target field in seconds. This tool evaluates expressions in real time and shows the match count and results, making it a handy companion for learning and debugging JSONPath syntax.

How to Use

1. Paste JSON data
2. Enter a JSONPath expression (starting with $)
3. See the match count and extracted results in real time

FAQ

What is the common JSONPath syntax?

$ for the root, .key for a child key, [*] for all array elements, [0] for an index, ..key for recursive search, [?(@.price<10)] for filtering, and [0:2] for slicing.

Why must the expression start with $?

$ denotes the root of the JSON document and is the required starting symbol of the JSONPath spec; expressions starting from a child node are invalid.

Does an empty result mean the expression is wrong?

Not necessarily. A valid expression with no matches returns an empty array — check that key casing and nesting levels match your actual data.
