JSON Path Tester

Evaluate JSONPath expressions against JSON data — 100% local processing

How to use JSON Path Tester

Paste your JSON data, enter a JSONPath expression (e.g. $.store.book[*].author), and click Evaluate. Matching values and their paths are displayed in a table.

Why test locally?

JSON data often contains API responses, user data, and configuration secrets. Devault evaluates JSONPath entirely in your browser so nothing leaves your machine.
