- 1.Paste your JSON Enter the JSON document you want to query in the input panel.
- 2.Type a JSONPath expression Enter a JSONPath expression in the query field, for example $.users[*].email or $.store.book[?(@.price < 10)].
- 3.See the results Matching nodes are shown in the results panel and highlighted in the source JSON.
- 4.Refine your query Adjust the expression and results update instantly until you get the data you need.
JSONPath Tester & JSON Developer Standards
JSON is the standard format for web APIs and modern applications. Using the JSONPath Tester helps you check syntax, catch formatting errors, and keep your data clean and readable.
Zero-Server Security
All data entered into JSONPath Tester runs directly inside your browser sandbox. Nothing is ever sent across the network or saved on remote servers.
Clean & CI/CD Ready
Well-formatted JSON prevents runtime syntax bugs, makes code reviews easier, and ensures smooth API data exchange.
JSONPath Tester Frequently Asked Questions
What is JSONPath?
JSONPath is a query language for JSON, analogous to XPath for XML. It lets you navigate and extract values from JSON using path expressions. It is widely used in APIs, testing tools, and configuration systems.
What JSONPath syntax is supported?
This tool supports the standard JSONPath operators: $ (root), . (child), .. (recursive descent), * (wildcard), [n] (array index), [start:end] (slice), [?(expression)] (filter), and @ (current node in filter).
What does $..price return?
The .. operator is the recursive descent operator. $..price returns all values with the key 'price' anywhere in the document, regardless of depth.
Can I use filter expressions?
Yes. Filter expressions use the [?(@.property operator value)] syntax. For example, $.books[?(@.price < 20)] returns all book objects where price is less than 20.
Are results shown as a JSON array?
Yes. The results panel shows matching values as a JSON array. If a single value matches, it appears as a one-element array. If no values match, an empty array is returned.
Can this tool handle large, complex JSON payloads?
Yes. Because the tool operates directly inside modern V8 JavaScript execution engines, it easily processes complex multi-megabyte payloads containing thousands of nested keys with negligible latency.
Are my proprietary payloads or secrets stored or cached?
No. BeYourTools implements zero tracking, zero telemetries, and zero database persistence. Everything stays strictly inside your browser memory and disappears the moment your tab is closed.
