A lightweight path evaluator for quickly pulling a value out of a JSON document, entirely in your browser.
About the JSONPath Finder
Digging a single value out of a large JSON document by hand is slow. A path expression lets you point straight at it.
This tool evaluates a dot and bracket path, such as $.user.address.city or user.roles[1], against your JSON and shows the matched value.
It runs in your browser, so even sensitive JSON stays private.

Frequently asked questions
- What path syntax is supported?
- A practical subset of JSONPath: an optional $ root, dot notation for object keys and bracket notation with an index for arrays, for example $.items[2].name.
- Does it support wildcards or filters?
- Not yet. It focuses on direct paths to a single value, which covers the most common lookups.
- What if the path does not match?
- If a key or index does not exist you will see 'undefined (no match)', and invalid JSON or paths show a clear error message.
