JSONPath Validator Online
Validate, test, and extract JSONPath expressions instantly in your browser — fast, private, and secure. Paste JSON on the left, add a JSONPath expression, and see output on the right.
JSON Input
Tip: For very large JSON, keep the JSON panel collapsed and use the Tree.
Auto-validate: runs after 700 ms of no typing
💡 Example: $.store.book[*].author — extracts all book authors.
Tip: If you get no results, validate the JSON structure first and try building the path step-by-step.

JSONPath Validator Online
Need a JSONPath validator and online JSONPath checker that returns results instantly and keeps your data private?
This tool lets you test, validate and evaluate JSONPath expressions (RFC 9535) directly in your browser — no uploads or backend processing required.
Paste JSON, enter a JSONPath expression, and extract values in seconds.

What is JSONPath?
JSONPath is a query language for selecting and extracting values from JSON documents using path expressions. It’s often compared to XPath (for XML), but designed specifically for JSON structures.
Example:
$.store.book[*].author
The expression above returns all book authors from a JSON object. In practice, JSONPath is used for API testing, debugging nested responses, filtering arrays, and extracting specific fields (like IDs, names, prices, or URLs).
While the original JSONPath specification by Stefan Gößner dates back to the mid-2000s, a formal standard was published in RFC 9535. Implementations may behave differently; this validator follows the RFC 9535 behavior. Read more about common JSONPath differences.

Why use this JSONPath validator?
- ⚡ Instant results to debug JSONPath faster
- 🔒 Privacy-first: runs 100% in your browser (no uploads)
- 🧠 Handles deeply nested JSON and complex structures
- 🧩 Full RFC 9535 support including filters, wildcards and array queries
- 🧪 Great for API work: quickly validate paths before using them in code
- 📱 Works on desktop and mobile
- 📖 Need to debug complex expressions? See our JSONPath debugging guide.
How to use the JSONPath tester
- Paste JSON into the left panel (or load an example).
- Enter a JSONPath expression (example:
$.users[*].email). - Click Validate & Extract (or just type and let auto-validate run).
- Copy or download the output.
If you get no results, the JSONPath is often correct but the structure isn’t what you expect.
Try building the path step-by-step: $ → $.users → $.users[*].
JSONPath examples you can copy-paste
| Goal | JSONPath expression | What you get |
|---|---|---|
| Root object | $ | The full JSON |
| All items in an array | $.users[*] | All users |
| All authors | $.store.book[*].author | List of authors |
| Single field | $.store.bicycle.color | "red" |
| Filter by numeric value | $.products[?(@.price > 10)] | Products with price > 10 |
| Filter by string equality | $.store.book[?(@.category == 'fiction')] | Fiction books |
| Pick first item | $.store.book[0] | First book object |
| Extract nested field after filtering | $.users[?(@.country == 'Romania')].name | Names of users from Romania |
| All IDs | $..id | All id fields found anywhere |
| Filter by boolean | $.users[?(@.active == true)].name | Names of active users |
| Filter by regex | $.users[?(@.email =~ /@example\.com$/)] | Users with emails from example.com |
Tip: if your expression fails in one environment but works in another, JSONPath behavior may vary by implementation. This tool aims to be consistent and standards-aligned (RFC 9535).
