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.

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.

Key features

Dot and bracket path notation
Works with nested objects and arrays
Clear errors for bad paths
Local, private evaluation

How to use

1Paste your JSON.
2Enter a path like $.user.roles[0].
3Read and copy the matched value.

Examples

Read an array item

Input: $.user.roles[0]

Output: admin

The path walks into user, then roles, then the first array element.
