Does this support the full JSONPath specification?

No — it supports basic dot notation and bracket array indexing, not filter expressions (?()), wildcards (*), or recursive descent (..) from the full spec.

What does it show if the path doesn't exist?

It shows "undefined (path not found)", making it clear the path didn't resolve to any value rather than silently showing nothing.

Can I start my path without the leading $.?

Yes — the leading $. is optional and stripped automatically if present.

Is my JSON data uploaded anywhere?

No — path evaluation happens entirely in your browser.

Can I use this to build a path for use in JavaScript code?

Yes — once you've confirmed the right path here, the equivalent JavaScript would use the same dot/bracket access pattern directly on your parsed object.

Need to use JSON Path Tester right now?

Digging a specific value out of a deeply nested JSON structure — especially one with arrays inside objects inside more arrays — is easy to get wrong by hand, with a typo in a key name or an off-by-one array index silently returning undefined. This tool lets you write a path expression against your JSON and see exactly what it resolves to, live, as you type.

"Book A"

Supports basic dot and bracket-index paths (e.g. $.a.b[0].c) — not the full JSONPath specification (filters, wildcards, slices).

About JSON Path Tester

It supports the everyday path syntax most developers actually reach for: dot notation for object keys (`$.store.book`) and bracket notation for array indices (`[0]`), chained together freely. This covers the vast majority of real-world 'grab this one value out of a JSON blob' needs without requiring the full JSONPath specification's filter expressions or wildcards.

This is useful for figuring out the correct path to extract a value in code (testing it here first before writing `data.store.book[0].title` in your actual script), debugging why a path expression isn't returning what you expect, or just exploring an unfamiliar JSON structure interactively.

How it works

Paste your JSON. Any valid, potentially deeply nested JSON document.
Write a path expression. Dot notation for keys, brackets for array indices.
See the resolved value live. Updates instantly as you edit the path.
